CompactLogix Packaged Controllers
Catalog Numbers 1769-L23E-QB1B, 1769-L23E-QBFC1B, 1769-L23-QBFC1B IMPORTANT The series B controllers are compatible only with the controller firmware and the RSLogix 5000
software versions as indicated in the table below.
Attempting to use controllers with incompatible software and firmware revisions can result in
the following:
• An inability to connect to the series B controller in RSLogix 5000 software
• Unsuccessful firmware upgrades in ControlFLASH™ or AutoFlash utilities In this example, these expansion I/O modules and bus current draws are planned for use with the
1769-L23E-QBFC1B packaged controller. The total bus current draw of the Compact I/O modules (310 mA) is less than the total available
bus current of the packaged controller (450 mA). These planned expansion I/O modules are
within the limits of the 1769-L23E-QBFC1B packaged controller. Panel Mount the System
To mount your system to a panel, complete these steps.
1. Using the assembled system as a template, carefully mark the center of all mounting holes
on the panel.
2. Remove the system and drill and tap the mounting holes for the recommended M4 or #8
screws.
3. Place the grounding panel (if used) and CompactLogix system on the panel to check for
proper hole alignment.
4. Insert the recommended screws into the mounting tabs on the packaged controller and
expansion modules (if used) and tighten To begin wiring your embedded I/O removable terminal blocks, loosen the screws at the top and
bottom of the removable terminal block and remove the removable terminal block from the
packaged controller. • All analog I/O commons (ANLG COM) are connected in the analog I/O card of the
packaged controller. The analog common (ANLG COM) is not connected to earth
ground inside the packaged controller.
• Analog I/O channels are not isolated from each other.
• Use Belden 8761 (or equivalent) shielded wire.
• Under normal conditions, the drain wire and shield junction must be connected to earth
ground via a panel or DIN rail mounting screw at the analog I/O removable terminal
block end. Keep the shield connection to ground as short as possible.
• To ensure optimum accuracy, limit overall cable impedance by keeping your cable as
short as possible. Plan to place the packaged controller as close to your sensors or
actuators as your application permits.(1)
• If multiple power supplies are used with analog inputs:
• the power supply commons must be connected.
• do not exceed the specified isolation voltage.
• The embedded analog I/O does not provide loop power for analog inputs. Use a power
supply that matches the input transmitter specifications.
• Differential analog inputs are more immune to noise than single-ended analog inputs.
• Voltage outputs (Vout 0+ and Vout 1+) of the analog I/O are referenced to ANLG
COM. Load resistance for a voltage output channel must be equal to or greater than 1
K.
• Current outputs (Iout 0+ and Iout 1+) of the analog I/O source current that returns to
ANLG COM. Load resistance for a current output channel must remain between
0…300 .
• Voltages on Vin+, V/Iin-, and Iin+ of the analog I/O must be within 0 to +10V DC of
analog common. • Input and output channels are isolated from the packaged controller. Input channels are
isolated from one another; output channels are not.
• Shielded cable is required for high-speed input signals A, B, and Z. Use individually
shielded, twisted-pair cable (or the type recommended by the encoder manufacturer) for
lengths up to 300 m (1000 ft).
• Route field wiring away from any other wiring and as far as possible from sources of
electrical noise, such as motors, transformers, contactors, and AC devices.
• Routing field wiring in a grounded conduit can reduce electrical noise.
• If field wiring must cross AC or power cables, ensure that they cross at right angles.
• Make sure the system is properly grounded using these guidelines:
– This product is intended to be mounted to a well-grounded mounting surface such
as a metal panel. Additional grounding connections from the packaged controller’s
mounting tabs or DIN rail (if used) are only required when the mounting surface is
non-conductive and cannot be grounded.
– Keep the shield connection to ground as short as possible.
– Ground the shield drain wire only at the HSC input end, except where
high-frequency noise is present. Digital Inputs Status Indicators
There is one status indicator for each digital input point of the CompactLogix packaged
controller. When an input is ON, the corresponding input light is on (amber).
Digital Outputs Status Indicators
There is one status indicator for each digital output point of the CompactLogix packaged
controller. When an output is ON, the corresponding output light is on (amber).
Analog I/O Status Indicator
The analog I/O have one status indicator - the OK status indicator. If the indicator is green, the
analog I/O have power, have passed internal diagnostics, and are communicating properly. If
analog I/O OK indicator is off, a fault is present.
High-speed Counter Status Indicators
The high-speed counters have 12 status indicators. 1747-L511 1747-L514 1747-L524 1747-L531 1747-L532 1747-L533 1747-L541 1747-L543 1747-L551 1747-L552 1747-L553 1756-L55 1756-L55M12 1756-L55M13 1756-L55M14 1756-L55M16 1756-L55M22 1756-L55M23 1756-L55M24 1747-L542 1756-L60M03SE 1756-L61 1756-L61RMCN1 1756-L61RMEN1 1756-L61S 1756-L62 1756-L62S 1756-L63 1756-L63S 1756-L63XT 1756-L64 1756-L65 1756-L71 1756-L71S 1756-L72 1756-L72S 1756-L73 1756-L73S 1756-L73SXT 1756-L73XT 1756-L7SP 1756-L7SPXT 1756-LSC8XIB8I 1756-LSP 1769-L16ER-BB1B 1769-L18ER-BB1B 1769-L18ERM-BB1B 1769-L23E-QB1B 1769-L23E-QBFC1B 1769-L23-QBFC1B 1769-L24ER-QB1B 1769-L24ER-QBFC1B 1769-L27ERM-QBFC1B 1769-L30ER 1769-L30ERM 1769-L30ER-NSE 1769-L31 1769-L32C 1769-L32E 1769-L33ER 1769-L33ERM 1769-L35CR 1769-L35E 1769-L36ERM
