Information About 1756-IA32

The Allen-Bradley 1756-IA32 is a ControlLogix AC input module that is primarily used to interface input or signaling devices that provides AC input signals with range of 74-132VAC. This module is a high-density input module, featuring Thirty-Two (32) input channels, grouped in Two (2), having Sixteen (16) channels per group. This module has group to group isolation, allowing the module to function even if a group has malfunctioned. Additionally, it features an input to backplane isolation however, it has no isolation between input channels.

The 1756-IA32 is part of the ControlLogix Programmable Automation Controller (PAC) product family. Each channel of this input module has a fixed hardware delay such as 1.5 ms delay in the OFF to ON transition and 1 ms delay in the ON to OFF transition. A user configurable delay may also be set with filter time options of 1 ms or 2 ms for OFF to ON transition and 9 ms or 18 ms for the ON to OFF transition.

To terminate input signals to the 1756-IA32, Removable Terminal Block (RTB) modules are required. Compatible RTB modules include 1756-TBCH which is a cage clamp terminal and 1756-TBSH which is a spring clamp terminal.

This module has a current draw of 165 mA at 5.1V, 2 mA at 24VDC and consumes a backplane power of 0.9 Watts with Power dissipation of 6.1 Watts at 60 Degree Celsius and Thermal Dissipation of 20.8 BTU/Hr.
