Description
Description
The Allen-Bradley 1746-IO12DC is a combination I/O module designed for the SLC 500 programmable controller system. This module provides a space-saving solution by integrating both digital inputs and relay outputs into a single slot. It features 6 DC input points and 6 relay output points, making it suitable for applications requiring a mix of signal monitoring and load switching within a compact footprint.
Features
- 6 DC Input points (10-30 VDC range).
- 6 Relay Output points for flexible load switching.
- Integrated design reduces rack space requirements in SLC 500 chassis.
- Designed for standard industrial control environments.
- Status indicators for monitoring I/O point activity.
Applications
This module is commonly utilized in industrial automation tasks where limited chassis space necessitates a high-density combination of discrete inputs and relay outputs. Typical applications include machine control, process monitoring, and small-scale automation systems where direct control of actuators or contactors via relay outputs is required alongside DC sensor inputs.
