SERIES CLS200

SPECIFICATION SHEET

Compact Loop System,

Providing Powerful Control

in a 1/8 DIN Package

Watlow’s SERIES CLS200 is a powerful line of controllers,

combining performance and flexibility with compact design.

The 4. 8 and 16 loop versions provide complete controller

solutions for a broad range of applications. Support for

multiple types of sensor inputs is available, including

thermocouples, RTDs, linear voltage, current and frequency.

Each controller can operate as a stand-alone system, and

includes built-in serial communications for computer interface

and data acquisition. Optional programmable ramp and soak

features allow complex batch processing and sequencing.

An enhanced feature option offers cascade control, ratio

control, differential control, process variable retransmit and

remote analog set point.

The SERIES CLS200 controllers are UL® and C-UL® listed and

meet the requirements of the European Community EMC

Directive and carry the CE mark.

Features and Benefits

Sensor failure detection

• Reduces time troubleshooting reversed, shorted and

open sensors

High/low process and deviation alarms for each input

• Integrates as needed to integrate with PLC and other

control elements

34 digital outputs

• Provides flexible configuration

• Allows use of outputs as needed for control and alarms

EIA/TIA-232 and 485 communications

• Connects to software for easy configuration and operation

• Allows integration with controllers and software

DAC and SDAC Modules

The optional DAC and SDAC modules are available for

Watlow SERIES CLS200 controllers.

DAC

The DAC (digital to analog converter) converts one or two

of the controller’s distributed zero crossing (DZC) output

signals to analog signals. Each output is field configurable

for 4-20mA(dc), 0-5VDC or 0-10VDC.

SDAC

The SDAC (serial digital to analog converter) converts

one controller output to a precise analog voltage or

current signal. The unit is typically used for process variable

retransmit, open-loop control, motor or belt speed control,

or phase-angle fired SCR power controllers. The SDAC bears

the CE mark and is UL® and C-UL® listed.

Firmware Options

Choose firmware with the features needed for the

application:

• Standard—includes closed-loop PID control, auto-tune,

alarms, job memory and failed sensor detection.

• Ramp and soak—includes the standard firmware

features with the addition of ramp and soak and process

variable retransmit. Each channel can be configured for

standard PID control or ramp and soak operation. Unused

control outputs on any channel can be configured for

retransmition.

• Enhanced features— includes the standard firmware

features with the addition of process variable retransmit,

remote analog set point, cascade control, ratio control

and differential control algorithms. Each channel can be

configured for standard PID controller or one of the other

control algorithms. Each channel of cascade control or

remote analog set point requires two controller channels.

Unused control outputs on any channel can be

configured for retransmit.

Because the SERIES CLS200 has no onboard analog

outputs, applications that use process variable retransmit

typically require one SDAC module per retransmitted

signal.
