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.
LH5946 Steststill Monitor继电器模块通过监视没有外部传感器的Remanence电压，可在单相和三相电动机（最高690V）上进行安全停水检测。监视器继电器模块的设计使用断裂的检测，并提供三个正常开放和一个正常关闭的正式安全接触。Stantstill Monitor继电器模块可在可调节的20至400mV和0.2至4V电压响应范围内使用，配备了LED状态指标和可调节的时间延迟；半导体输出监控继电器状态。可用于24VDC，120VAC和230VAC电源电压，价格为349美元。
