Product Description

ABB 1SVR730850R0300 CM-ENS.31S Liquid Level Relay is a precision control device designed for monitoring conductive liquid levels. It features a DIN Rail mountable housing with compact dimensions of 113.4mm (L) × 22.5mm (W) × 113.4mm (D), making it suitable for efficient panel mounting and board packing.

This relay supports a single input voltage of 240V AC/DC with a rated SPDT relay output that provides reliable switching to control pumps or alarms based on liquid levels. The device offers adjustable sensitivity ranging from 0.1 kΩ to 1000 kΩ, allowing calibration for various liquid types and operating conditions.

The front panel includes a potentiometer for easy manual adjustment of sensitivity and a selectable on/off delay to prevent nuisance tripping due to rapid level changes. LED indicator lights provide real-time visual diagnostics for operational state verification.

Constructed with a flame-retardant housing for enhanced safety, this relay operates effectively within -25°C to 60°C, and is rated for IP20 and IP50 protection levels, suitable for a variety of industrial environments. The screw terminal connections ensure secure wire retention and minimal maintenance.
