Allen-Bradley 1756-IF16 ControlLogix 16-Channel Analog Input Module

Product Overview

The Allen-Bradley 1756-IF16 is a ControlLogix analog input module designed to acquire voltage and current signals from field devices such as transmitters, sensors, potentiometers, and process instruments. It converts analog field signals into digital data for ControlLogix controllers, enabling accurate monitoring and control in automation systems.123

This module supports 16 single-ended, 8 differential, or 4 high-speed differential input channels, depending on wiring configuration.123 It accepts multiple input ranges including ±10.25V, 0–10.25V, 0–5.125V, and 0–20.5mA, with up to 16-bit resolution for stable and precise measurement.124 The module installs into any slot of a ControlLogix chassis and communicates with the controller through the backplane.

The 1756-IF16 is commonly used in process control, machine automation, packaging, material handling, HVAC monitoring, and general industrial applications where reliable analog signal acquisition is required.

Applications

The 1756-IF16 is suitable for:

Process monitoring for pressure, flow, level, and temperature transmitters
Machine automation for analog sensor feedback and position measurement
Packaging and material handling systems requiring analog signal acquisition
HVAC and utility monitoring for voltage/current-based instrumentation
Test stands, pilot lines, and general industrial control panels
System expansion where additional analog inputs are needed in ControlLogix systems

Why Choose the 1756-IF16

The 1756-IF16 provides a practical balance between channel density, signal flexibility, and measurement precision. With up to 16 single-ended channels in one module, it helps reduce rack space and wiring complexity compared with lower-density analog input modules. Its differential and high-speed differential modes also make it suitable for applications that require better noise immunity or faster data updates.237

For procurement and integration teams, this module is a reliable option when replacing existing ControlLogix analog input cards, expanding analog I/O capacity, or standardizing spare parts for voltage and current signal acquisition.

Compatibility

The 1756-IF16 installs into a ControlLogix 1756 chassis and requires a compatible removable terminal block, typically 1756-TBCH or 1756-TBS6H.125 It is configured using RSLogix 5000 or Studio 5000 Logix Designer, and communicates with ControlLogix controllers through the backplane.

Before ordering, please confirm the required wiring configuration, input signal type, terminal block type, and compatibility with your existing ControlLogix system.
