AutomationDirect's Safety Speed Monitor Relays

The BH5932 speed monitor relay module is designed to monitor two sensor inputs that are detecting rotating targets on a motor shaft. This monitor relay features two-channel operation and can be used for standstill and overspeed monitoring of three-phase motors.
The LH5946 standstill monitor relay module provides safe standstill detection on single-phase and three-phase motors (up to 690V) by monitoring remanence voltage without external sensors. The monitor relay modules are designed with broken wire detection and provide three normally-open and one normally-closed positive-guided safety contacts.
