A-B 1769-L24ER-QBFC1B CompactLogix 5370 L2 Controller

Additional suppression is especially important if your inductive device is in series with or parallel to hard contacts, 

such as push buttons or selector switches.

Add a suppression device directly across the coil of an inductive device. The suppression 

device reduces the effects of voltage transients that are caused by interrupting the current to that device and to prolong the life of the switch contacts.

Analog I/O Modules

Choose analog, thermocouple, or RTD modules for these features:

• Individually configurable channels

• Ability to enable and disable channels individually

• Onboard scaling

• Auto calibration of inputs

• Online configuration

• Selectable input filters

• Over-range and under-range detection and indication

• Selectable response to a broken input sensor

• Selectable power source

• Input modules offer both single-ended or differential inputs

• Ability to direct output device operation during an abnormal condition

• High accuracy ratings

The data can be configured on board each module as:

• Engineering Units in volts or milliamps.

• Scaled-for-PID.

• Percent of range.

• Raw/Proportional Data for maximum resolution.

Each 1769 I/O module has a distance rating. 

In 1769 systems, the distance rating is the number of modules between the specific module and the 1769 power supply. 

In a 1768 system, the distance rating is the number of modules between the specific I/O module and the 1768 controller.

I/O Module Overview Each

I/O module includes a built-in removable terminal block with fingersafe cover for connections to I/O sensors and actuators.

The terminal block is behind a door at the front of the module. I/O wiring can be routed from beneath the module to the I/O terminals.

• Once the modules are locked together, the system becomes a rugged assembly.

• Upper and lower tongue-and-groove slots guide the module during installation and secure the module within the system.

• Removable terminal blocks help ease the wiring task.

• Self-lifting, field-wire pressure plates cut installation time.

• The patented bus connector with the lock function enables consistent and system communication.

• A color bar is provided on the front of the module.

• Digital and field circuits are optically isolated.

The 1769 Compact I/O™ modules can be used in the following applications:

• With a CompactLogix™ controller

• For expansion I/O in a MicroLogix™ 1500 controller assembly 

• In an assembly with a 1769-ADN DeviceNet adapter

• In an assembly with a 1769-AENTR Ethernet adapter.

Unless connected to a MicroLogix 1500 base, each bank of I/O modules must include its own power supply.

Install the I/O modules on a panel with two mounting screws or on a DIN rail.
