- Provides four SLC 500 module positions
- Uses a modular SLC 500 power-supply and I/O architecture
- Requires enclosure sizing from the completed chassis configuration
Allen-Bradley 1746-A4 is the four-slot chassis for compact SLC 500 modular stations.
Selection depends on the processor or communication adapter, I/O count and side-mounted power supply required by the machine.
Before installation, confirm backplane condition, module keying, grounding, enclosure clearance and the power calculation for the complete station.
Availability, condition, price, and shipping time for 1746-A4 are confirmed during quotation.
