Safety Speed Relay Modules monitor single- and 3-phase motors.
August 1, 2012 -
Designed to monitor 2 sensor inputs that are detecting rotating targets on motor shaft, Model BH5932 has adjustable range of 10-20,000 impulses/min and can be used for standstill and overspeed monitoring of 3-phase motors. Model LH5946, available in adjustable 20-400 mV and 0.2-4 V voltage response ranges, provides standstill detection on single- and 3-phase motors up to 690 V by monitoring remanence voltage without external sensors. Both are available for 24 Vdc, 120 Vac, and 230 Vac supply voltages.

Safety Speed Monitor Relays now available from AutomationDirect
Cumming, GA --- AutomationDirect has added Dold safety speed relay modules to its line of safety products.
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. When used as a standstill monitor, a switch point is set just above the "safe" or normal operating speed. When motor speed rises above this setting, the relay opens to protect against motor damage. The BH5932 relay module has an adjustable impulse-per-minute (IPM) range of 10 to 20,000 IPM, LED status indicators, two PNP sensor inputs, and two normally-open and one normally-closed positive-guided contacts. Available for 24VDC, 120VAC, and 230VAC supply voltages, prices start at $279.
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. Available for 24VDC, 120VAC, and 230VAC supply voltages, prices start at $349.
Safety speed relay modules are cULus, CE, and RoHS approved and are backed with a one-year warranty. For more information, visit: www.automationdirect.com/safety-speed-relay.
