LR44/3 VOLTAGE MONITORING RELAY

Product Description

The LR44/3 is a DIN-rail mounted logic / voltage monitoring relay designed to control and balance operation between multiple loads such as motors, compressors, and pumps. It monitors external voltage-free contacts and automatically alternates outputs to ensure equal running time and improved system efficiency.

It is commonly used in industrial automation systems where multiple equipment units need controlled sequencing and load sharing.

Key Features

• Logic control relay for load balancing and sequencing
• Monitors 3 external voltage-free (N.O.) input contacts
• 3 x SPNO relay outputs (switching outputs)
• Automatic rotation (alternation) of outputs on each input trigger
• “Help function” allows additional relays to energize when required
• Wide auxiliary supply range (100–230V AC/DC)
• DIN rail mounting (44 mm compact housing)
• LED indicators for supply and relay status
• Microprocessor-based control logic
• Suitable for motors, pumps, compressors, and generator systems
