- Dual Mounting Options: Flexible installation via standard 35mm DIN rail or direct panel mount to suit custom industrial enclosures.
- Interposing Relay Capability: Optimized for use with interposing relays to control high-voltage 120/240V AC loads while maintaining 24V DC logic isolation.
Industry Applications
- Discrete Load Actuation: Direct control of 24V DC pneumatic valves, stack lights, and small motor starters.
- Packaging & Material Handling: Driving high-speed diverters and sorters where sub-millisecond response times are critical.
- Distributed I/O Banks: Expanding the I/O capacity of CompactLogix 1769-L3x or MicroLogix 1500 systems.
Installation & Maintenance Notes
- Distance Rating: Ensure the module is installed within 8 slots of its 1769-series power supply (e.g., 1769-PA4 or PB4).
- Wiring Guidelines: Use 22–14 AWG solid wire or 22–16 AWG stranded wire to ensure secure, finger-safe connections within the 1769-RTBN18 terminal block.
