Beskrivelse
Allen-Bradley 1746-IO8 SLC 500 AC Digital Combination Module
The Allen-Bradley 1746-IO8 is a versatile combination digital I/O module engineered for the SLC 500 modular control architecture. Weighing approximately 0.28 kg (0.62 lbs), this compact card features 4 digital 120V AC inputs and 4 Normally Open (N.O.) relay contact outputs in a single common group, providing an efficient solution for small-to-medium industrial control tasks.
Key System & Hazardous Area Features
Approved for Class 1, Division 2 (Groups A, B, C, D) hazardous environments, the 1746-IO8 operates with an AC input voltage range of 85 to 132V AC. Relay outputs support switching up to 1.5A at 120V AC and 1.2A at 24V DC. With low thermal dissipation (3W total aggregate), NEMA ICS 2-230 noise immunity, and CE/CSA/C-UL compliance, it delivers high operational stability under heavy shock (30G) and vibration conditions.

Installation & Handling Guidelines
- Chassis Slot Installation: Mount into any available non-CPU slot (slots 1 through 30) within an SLC 500 1746 I/O chassis. Slot 0 is reserved strictly for the CPU controller.
- Hazardous Location Compliance: When operating in Class 1, Div 2 locations, ensure all field wiring connections are secured and power is disconnected prior to insertion or removal.
- Wiring Layout & Cable Routing: Route input and output field power cabling separately from communication and sensor signal lines to prevent induced electrical noise.
