Description

The Allen-Bradley 1756-IF16 is a ControlLogix non-isolated analog voltage and current input module designed to convert analog field signals into digital data for processing by ControlLogix controllers. It provides 16 single-ended, 8 differential, or 4 high-speed differential input channels with selectable input ranges including +/-10V, 0...10V, 0...5V, and 0...20 mA. Operating across the ControlLogix backplane using Producer/Consumer technology, the 1756-IF16 enables efficient input data sharing across multiple controllers on the network without requiring separate polling mechanisms.

Features

Supports 16 single-ended, 8 differential, or 4 high-speed differential input channels
Selectable input ranges: +/-10V DC, 0...10V DC, 0...5V DC, and 0...20 mA DC
On-board digital filtering and input scaling to engineering units
Real-time sampling with customizable channel scanning speeds
Under-range, over-range, and wire-off fault detection per channel
Compatible with 36-pin Removable Terminal Block (RTB) housings

Applications

Process control monitoring in oil, gas, and chemical facilities
Temperature, pressure, and flow monitoring systems
Factory automation analog signal processing
Water and wastewater treatment monitoring
Power generation and energy management systems

Installation Guidelines

Ensure chassis power is off or verify area non-hazardous status before inserting or removing the module.
Insert the module into any available slot of a ControlLogix 1756 chassis.
Secure wiring using an approved 36-pin Removable Terminal Block (1756-TBCH or 1756-TBS6H).
Use shielded twisted-pair cables for analog signal connections to mitigate EMI/RFI noise.
Connect cable shields to designated shield grounding points as instructed in system documentation.
Provide adequate chassis clearance to support proper cooling air ventilation.

Product Documentation

Technical Datasheet (PDF) Complete specifications and technical drawings.

What input signal ranges are supported by the module?

The module supports +/-10V DC, 0...10V DC, 0...5V DC, and 0...20 mA DC input ranges.

Which removable terminal blocks are compatible with the device?

It is compatible with 36-pin Removable Terminal Blocks, specifically the 1756-TBCH (cage clamp) and 1756-TBS6H (spring clamp).

Does channel-to-channel isolation exist on this analog input module?
