  • 15-bit to 16-bit resolution for precise analog measurements
  • Overvoltage protection withstands 30 V DC for reliable operation
  • 73 W power draw keeps energy use low
  • Single-slot module fits standard ControlLogix chassis
  • 4 000 analog I/O limit supports large-scale automation

Analog input module for ControlLogix systems

The Allen-Bradley 1756-IF8 SER B is an analog input module designed for ControlLogix programmable logic controllers. It occupies a single slot in a local chassis or any compatible I/O rack. The module provides eight channels for connecting actuators and I/O sensors in industrial automation environments.

15 to 16-bit resolution with 4000 signal capacity

Resolution reaches 15 bits at +/-10V DC and 16 bits for other signal types, with specific ranges of 160 µV/count at 0-10V DC, 320 µV/count at +/-10V DC, 0.32 µA/count for 0-20 mA, and 80 µV/count for 0-5V DC and 0-20.5 mA. The module handles up to 4000 analog I/O signals and requires 1.73 watts of power. Overvoltage protection withstands 30V DC and 8V DC, marking the limit for safe signal input.

Finger-safe cover and removable terminal block

A finger-safe cover is pre-installed to protect personnel during maintenance. One built-in removable terminal block ships with the module, simplifying field wiring and module replacement without rewiring the entire installation. These accessories reduce downtime during service and improve safety compliance in panel builds.

Questions about this item

Will the 1756-IF8 module fit in the same ControlLogix chassis I already use for other 1756 I/O cards?

Yes, the 1756-IF8 is a single-slot ControlLogix module that mounts in any standard 1756 chassis or I/O rack you already have installed.

Which front-panel indicators confirm the 1756-IF8 is powered and communicating after I wire the removable terminal block?

The module’s status LED shows green when the 1.73 W backplane supply is healthy and the channel LEDs reflect live 15-bit or 16-bit conversions on each of the eight inputs.

Does the sealed 1756-IF8 package include the removable terminal block and finger-safe cover, or must I order them separately?

The sealed unit ships with one built-in removable terminal block and the finger-safe cover already installed; no extra parts are required for basic wiring.
