Description

The Allen-Bradley 1746-IB16 is a medium-density DC input module.Here is a detailed introduction to it:

I.Product Overview

The Allen-Bradley 1746-IB16 module has sixteen discrete current sink input channels for connecting to signal devices,providing a signal voltage range of 10~30VDC for each input channel of the module.The module is usually installed on any available I/O slot of the 1746 series chassis and consumes a certain amount of backplane current.

II.Product Features

High-performance processor:Although the 1746-IB16 module itself does not directly contain a processor,it is part of the PLC-5 controller and can benefit from the PLC-5’s high-performance processor to handle complex control algorithms and real-time control tasks.

Multiple I/O support:The PLC-5 controller supports a variety of input/output(I/O)modules,including the 1746-IB16,to meet the processing needs of various input and output signals.
