DC milliamp current monitoring relay for 4–20mA process signal supervision. Monitors a 1–20mA DC signal and trips when the current exceeds or falls below the adjustable setpoint. 230VAC auxiliary supply, 11 pin plug-in. Commonly used for monitoring 4–20mA process transmitter signals, flow sensor outputs, and pressure transducer signals.
Note: Requires ZB11 11-pin relay base socket (sold separately). For DIN rail retention, add CMAC Spring Clip. For AC current monitoring, see the RC15 or RC30.
