Features 

 Dual display Two 4-digit displays with 7 LED segments, each configurable for:     PV and SP (non adjustable) PV and SP (adjustable) PV and Ramping SP PV only Easier to configure Two different configuration levels (Configuration mode and set-up mode) provide easy access to parameters. A 4-digit security code prevents unauthorized changes. Moisture resistant front-face Meets NEMA 3 / IP65 front-face protection against dust and water. Universal input Accept seven different types of thermocouples, RTDs, current and voltage linear inputs. All inputs are configurable as standard. Universal power supply The UDC1200 and UDC1700 can operate on any line voltage from 90 Vac to 264 Vac at 50/60 Hz. A 24/48 Vac/dc model is available as an option. Easy upgrade All the option boards are jumper free and detected automatically by the instrument. Easy output selection All the outputs (including the control output) of the instrument can be changed to meet the exact   customer’s needs.

Alarm strategy 

 Two soft alarms for PV, deviation high/low/absolute. A special loop alarm is also provided to detect faults in the control loop by continuously analyzing the PV response to the control output. Alarm inhibit is available on power up and setpoint switching. Manual/Automatic mode Manual control (via bumpless transfer) is enabled by simply pressing the front-face AUTO/MAN key. The “SET” LED flashes and the output power is displayed on the lower display. Output can be adjusted with the upper and lower keys. Pre-tuning and self-tuning strategy   Pre-tuning is used to set up the PID parameters close to the optimum values, which the self-tuning algorithm uses to subsequently optimize the tuning parameters. Limit controller   Packaged in 1/16 DIN, the UDC1200 limit controller is designed to provide a safety shut-off and optional alarm for use in a wide variety of applications. Up to three outputs The UDC1200 and UDC1700 provide up to three outputs for time and current proportioning, duplex mode (heat/cool), PV or SP retransmission, and alarms. Setpoint ramp The current setpoint can ramp to a new-targeted setpoint by way of a user defined ramp rate. Dual setpoint Dual setpoint option is available on the UDC1200 and UDC1700. The current setpoint is selected by a digital input. This option is exclusive with UDC1200 limit model remote alarm reset. Communication An optional RS485 communications interface is available on the UDC1200 and UDC1700. It provides a link for up to 32 units and a host computer through ASCII or Modbus RTU protocol at up to 19200 baud.

Highly secure A non-volatile memory based on EEPROM technology ensures data integrity during loss of power supply, with retention of more than 100 years. A 4-digit security code prevents unauthorized or accidental change.

 Physical Description 

 The UDC1200 controller is housed in a 110 mm (4.33 inches) deep case with a standard UDC gray bezel. It can be mounted in a 1/16 DIN panel cutout.   The UDC1700 controller is housed in a 100 mm (3.94 inches) deep case and can be mounted in a 1/8 DIN panel cutout. By using the pre-assembled mounting fixture delivered with the unit, you can easily and securely install the controller into the panel cutout. Modular plug-in construction allows rapid access and saves time. All inputs and outputs are connected on the rear terminal block by screws. Operator Interface Four display combinations are offered to the operator. The upper 4-digit 7-segment display is always dedicated to monitor the PV. The lower display can show: 

  SETPOINT (read only)

  SETPOINT (adjustable) 

   RAMPING setpoint (ramp mode)

   BLANK 

 Universal 

Inputs All input types are available on any unit. Selection among the various types of inputs is made by prompt configuration. As soon as the Process Variable reaches the value of the input range limit, the controller displays a message. A sensor break indication is also provided. A configurable digital filter is available from 0.5 seconds to 100.0 seconds.

Outputs 

 Three types of outputs (RELAY, SSR driver or DC linear) are selectable for three outputs, through the model selection guide or by adding a plug-in module for outputs 1, 2 and 3. Outputs Algorithm The UDC1200 and UDC1700 are available with the following output algorithms: 

  Time proportional: ON/OFF or time proportional with electromechanical relay SPDT 2 A or SSR driver (open collector). 

  Current proportional: Supply directly proportional current or voltage signal to the final control elements which require 0 20 mA, 4 20 mA, 0-10 V or 0-5 V. 

  Time proportional duplex: Three duplex modes can be selected, either ON/OFF duplex, time proportional duplex (heat/cool with two proportional bands, two cycle times and deadband) or TPSC. 

  Current proportional duplex: In addition to the first current/voltage output, a second similar output with its own proportional band is provided. 

  Current/Time or Time/Current duplex: Provides a variation of traditional time or current duplex mode by mixing current and time proportioning together.

Control Algorithms

Four control algorithms can be set up through the configuration menu:  On/Off  PD + MR  PID  TPSC The TPSC (Three Position Step Control) control algorithm is dedicated to control valve positioning without slidewire feedback from the motor shaft.

Configuration

There are two levels of configuration. The SET-UP mode allows modification of current parameters such as tuning parameters, alarm values, setpoint limit, ramp enable, auto-manual mode enable and auto pretune enable. The CONFIGURATION mode is more oriented to unit personality: input selection, output 2 and 3 usage, alarm type, communication address and lockout code. The operator mode screens are only selectable via the configuration software only. For instance, the alarm value screen can be moved from setup mode to normal operator mode if desired.

Control Mode

Manual or automatic mode with bumpless transfer is standard feature. In manual mode, the operator can directly control the output through the two front face keys (raise and lower keys). The output value is monitored on the lower display.

Alarms

 Outputs 1, 2 and 3 can be used as alarms. Two electromechanical single pole double throw relays can activate external equipment when alarm setpoints are reached. An LED is also activated on the front-face. A direct or reverse acting alarm output can be configured. A logical combination of the two alarms: OR, AND or hysteresis (active when both alarms are active and inactive when both alarms are inactive) can be set which associates the two alarms status before energizing the relay. In order to detect a defective control loop, the controller can supply special loop alarm control by continually monitoring the PV response to output demand. A timer is automatically set up when any output is on saturation mode. When the timer reaches twice the reset time with no PV response, the loop alarm is activated. With this soft alarm there is no need for a heater circuit breaker, saving wiring time and costs.

Display

Dual, four-digit LED display with decimal point location configurable up to three places for linear ranges only.

Limit Controller

The UDC1200 1/16 DIN limit controller provides a latched relay output which is activated when the process parameters either exceed or fall bellow the desired value, providing a failsafe cut-off which has to be manually reset before the process can continue. The UDC1200 limit controller can be configured to be either a “high limit” unit where the delay will de-energize when the PV is above the limit setpoint, or a “low limit”, where the relay will drop out when the PV falls below the setpoint. A LED indicator shows when limits have been exceeded, and when the relay is latched out. The optional digital input allows a remote reset function.

Remote Setpoint Model

The UDC1700 1/8 DIN "R" model controller has a second input available that accepts either a linear or potentiometer input signal as a remote setpoint. The input signals accepted are field-configurable and are: 0-5 V, 1-5 V, 0-10 V, 2-10 V, 0-20 mA, 4-20 mA (factory set), 0-50 mV, 10-50 mV, 0 100 mV, or 0-2000 ohms.  This allows the controller to act as a "slave" controller accepting a setpoint value from a 'master' device such as a PLC or setpoint-programming controller (such as the DCP50, DCP100, DCP300, or DCP550 series).   The UDC1700R also includes a standard digital input allowing remote switching between the local setpoint and the remote setpoint value. Also standard in this model is "fuzzy" autotune software that minimizes process variable overshoot when responding to a setpoint change.

PC Software

The UDC1200 & 1700 are supported with PC software allowing you to quickly configure your device using configuration wizards, or to perform diagnostics.
