1746-IM16 Functional Description

The SLC 16 Point 240V AC Input Module 1746-IM16 is a discrete 16-channel AC input module designed for integration into the SLC 500 programmable controller system. This robust module is engineered to interface with high-voltage industrial field devices, accepting an input voltage range of 170-265V AC. 

Each of the sixteen points on the ALLEN BRADLEY 1746-IM16 Digital I/O Modules operates with a nominal voltage of 200/240V AC, making it suitable for directly monitoring the status of machinery and sensors commonly found in industrial environments.

Installation of the AB 1746-IM16 SLC 16 Point 240V AC Input Module is highly flexible, as it can be mounted in any available slot within a local or expansion SLC 500 chassis. A key feature is its use of a Removable Terminal Block (RTB), which simplifies wiring and maintenance procedures. The module exhibits specific operational characteristics, including signal transition delays of 35ms (OFF to ON) and 45ms (ON to OFF), ensuring reliable state detection. Furthermore, the Allen-Bradley 1746-IM16 provides effective electrical isolation, tested at 1500V, between the field wiring and the controller's backplane logic for enhanced system safety.

The operational robustness of the ALLEN BRADLEY 1746-IM16 is underscored by its compliance with industrial standards for noise immunity and its specified operating temperature range of 0 to 60°C. With a maximum off-state voltage of 50V AC and a low backplane current consumption, it is designed for reliable, long-term performance in demanding factory conditions. This Digital AC Input Modules 1746-IM16 AB  serves as a critical link for integrating high-voltage AC signals into an automated control system, providing essential data for the SLC 500 processor.
