Safety Speed Monitor Relays

Safety speed relay modules are cULus, CE, and RoHSafety speed relays.jpgS approved and are backed with a one-year warranty. 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. Available in adjustable 20 to 400mV and 0.2 to 4V voltage response ranges, standstill monitor relay modules are equipped with LED status indicators and adjustable time delay; semi conductor outputs monitor relay state.
