Description

The Allen Bradley 1756-IV16 is a ControlLogix digital DC sourcing input module. Designed for compatibility with the ControlLogix 1756 chassis system, this module receives discrete signal inputs from field devices and transfers input status to the system backplane. It requires a removable terminal block housing (RTB)—either the 1756-TBNH or 1756-TBSH—prior to mounting into the chassis. The 1756-IV16 provides 16 sourcing input channels configured in 2 groups of 8 points each, operating across a nominal supply voltage of 12/24V DC.

Features

16 digital sourcing inputs organized into two groups of 8 points.
Operating DC voltage range from 10V DC to 30V DC.
Configurable off-to-on hardware input delay plus user-selectable digital filter options.
Optical isolation rating up to 250V continuous.
Compatible with 1756-TBNH and 1756-TBSH removable terminal blocks.

Applications

Factory automation discrete sensing and position detection.
Machine tool limit switch and proximity switch monitoring.
Material handling equipment status feedback.
Process control interlock and discrete event monitoring.

Installation Guidelines

Ensure system power and backplane power are removed before installing or removing the module.
Securely wire field devices to the compatible 1756-TBNH or 1756-TBSH Removable Terminal Block (RTB) according to standard industrial wiring practices.
Align the module with the chassis slot guides and push firmly until the module latches into the ControlLogix backplane.
Route signal wiring away from high-voltage AC lines and high-frequency noise sources to mitigate EMI/RFI interference.
Maintain proper panel ventilation to prevent operating ambient temperatures from exceeding 60 degC.
