The module features a removable terminal block (RTB) located on the front face, allowing for easy wiring maintenance without disturbing field connections. The terminal block uses self-lifting pressure plates designed to accommodate up to two 14 AWG (2 mm squared) wires per screw terminal. Front-facing LED status indicators display the active state of each individual output point to assist with diagnostics and troubleshooting.
Ensure all power to the SLC 500 chassis and associated backplane is completely disconnected before inserting or removing the 1746-OA8 module. Mount the module into any available I/O slot of an SLC 500 chassis. Secure the module using the top and bottom retaining screws. To mitigate the effects of leakage current with solid-state outputs, apply an appropriate loading resistor in parallel with the load if necessary (e.g., a 15 kohm, 2W resistor for 120 Volt AC operation or a 15 kohm, 5W resistor for 240 Volt AC operation).
