Genuine Mors Smitt UB200 Voltage Monitoring Relay

Original Mors Smitt UB200 railway voltage monitoring relay module designed for rolling stock, signalling and industrial control systems.

This plug-in relay monitors battery voltage levels and disconnects auxiliary circuits when voltage drops below the configured threshold. The relay reconnects circuits automatically once voltage recovers.

Designed for railway and heavy industrial applications with high resistance to shock and vibration.
