Penerangan
Allen-Bradley 1746-IO4 SLC 500 AC Digital Combination Module
The Allen-Bradley 1746-IO4 is a compact combination digital I/O module designed for the SLC 500 rack-based PLC architecture. Weighing approximately 0.25 kg (0.55 lbs), this module features 2 digital AC inputs and 2 relay contact outputs arranged in a single common group, offering an space-efficient solution for small-scale 120V AC automation and device control.
Key System & Operational Features
Operating within a voltage range of 85 to 132V AC (47–63 Hz) for inputs, the 1746-IO4 dissipates just 0.27 Watts per input channel during operation. Its relay contact outputs handle a continuous current of up to 4A, supporting switching capacities of 1.5A at 120V AC and 1.2A at 24V DC. Front-panel status LEDs provide immediate channel diagnostics, while low backplane current consumption (30 mA @ 5V DC / 25 mA @ 24V DC) ensures optimal power rack budgeting.

Installation & Handling Guidelines
- Rack Slot Installation: Insert the module into any available slot of an SLC 500 chassis (except slot 0, reserved for CPU) until the top and bottom retaining levers click into place.
- Terminal Block Wiring: Terminal screws feature self-lifting pressure plates designed to accept up to two 14 AWG (2.0 mm²) copper conductors per terminal.
- Cable Separation: Route incoming AC main power feeds separately from low-voltage field sensor cabling to avoid EMI noise coupling.
