Reliance Electric S-67118C Analog Output Module

The Reliance Electric S-67118C Analog Output Module is a four‑channel, isolated analog output block designed for Reliance AutoMax PLC systems. Each channel is independently isolated from the others and from the logic plane, with 2500 V isolation to help protect control logic when interfacing with external field devices. The module delivers 12‑bit resolution per channel and supports either 0–10 V voltage outputs (up to 10 mA per channel) or 4–20 mA current outputs, depending on configuration. An integrated first‑order low‑pass filter provides a 100 Hz response to help reduce output noise and provide smoother control signals. Front‑face LED indicators aid diagnostics by displaying channel activity and fault conditions. Intended for AutoMax I/O backplanes, this module is commonly used to drive analog actuators and field instruments such as valves, position transducers, and process sensors in automation and process-control applications.
