ABB 1SVR730850R0200 Industrial Safety Relay Module

ABB 1SVR730850R0200 is an industrial level-monitoring relay module used for detecting liquid levels with conductivity sensors. In ABB’s CM-ENS family, it is described as a liquid level monitoring relay (1c/o) with a sensing range of 0.1–1000 kΩ, enabling a control output when a liquid level crosses a set threshold. Typical applications include water and wastewater treatment, chemical processing, and tank-level monitoring where reliable level sensing with electrodes or probes is required. The unit provides a single changeover contact suitable for triggering pumps, alarms, or safety interlocks in automation sequences, and is designed for integration into control panels. The single changeover output provides a direct interface to PLCs, relays, or safety circuits for straightforward process control. By interfacing directly with conductivity probes, it converts a liquid presence signal into an output that can be used by safety or process-control logic. The device is suitable for integration with automation systems that rely on simple level sensing.
