Schneider RM4LG01B Liquid Level Control Relay

Description

The RM4LG01B is a Liquid Level Control Relay from the RM4 range, manufactured by Schneider Electric. This device is specifically engineered to monitor and control the levels of conductive liquids in tanks or reservoirs. By utilizing probe sensors to detect liquid presence, the relay provides reliable switching functionality for pump-out (emptying) or pump-in (filling) applications, ensuring efficient process management in industrial water and chemical handling systems.

Features

• Precision liquid level monitoring for conductive liquids
• Adjustable sensitivity to accommodate various liquid types
• Reliable relay output for pump motor or valve control
• Designed for standard industrial DIN rail or panel installation

Applications

• Level control for water storage tanks
• Industrial chemical reservoirs
• Wastewater management systems
• Automated filling and emptying processes

Technical Specifications

Installation Guidelines

• Mounting: Ensure the relay is mounted vertically in a control cabinet protected from moisture and extreme heat.
• Probes: Install conductive probes at the required high and low levels. Ensure the common probe is submerged at the lowest point of the tank.
• Wiring: Connect the probes to the input terminals as per the wiring diagram. Use shielded cable for long runs to prevent interference from adjacent power lines.
• Sensitivity: Adjust the sensitivity dial on the front of the unit based on the conductivity of the specific liquid being monitored to ensure accurate switching.
