Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The Allen-Bradley 1746-NIO4I is a modular SLC-500 series analog combination I/O module providing two analog inputs (voltage or current) and two analog current outputs in a single slot. It integrates into fixed or modular SLC-500 racks (excluding slot 0 in Remote I/O setups) and communicates over the SLC backplane. Typical applications include on-machine analog signal acquisition and output in process control, laboratory systems, and incremental automation systems using the SLC-500 platform. The 1746-NIO4I supports mixed analog I/O within one module.
Best Suited For
- SLC-500 systems requiring mixed analog input/output in one slot
- On-machine analog signal processing (voltage or current inputs)
- Process control involving small analog channel counts
- Applications where backplane slot economy is required
