Description

The safety relay is composed of several relays and circuits, in order to complement each other's abnormal defects and achieve the complete function of the relay with correct and low malfunction, so that the lower the error and failure value, the higher the safety factor. Therefore, it is necessary to design a variety of safety relays to protect different levels of machinery, and the main goal is to protect machinery operators exposed to different levels of danger. The safety relay is a necessary control part in a safety loop. It accepts safety input, and through the judgment of the internal loop, deterministically outputs the switch signal to the control loop of the device. Simply put, the safety relays are all dual-channel signal types. Only when the signals of both channels are normal, the safety relay can work normally; during the working process, as long as the signal of any one of the channels is disconnected, the safety relay will stop outputting until the two channels are disconnected. All channel signals are normal and can work normally after reset.

Characteristic

1. When the emergency stop is released, the machine cannot restart suddenly;
2. In case of failure of the safety circuit of the machine, the power supply of the machine can be stopped;
3. When the safety circuit fails, the machine cannot be restarted;
4.fail safe control system which is cyber secure and insensitive to electro magnetic
5.Relays are ideal to use in excavator for signal transfer/repeat, safety interlocking functions (brake - doors), load on-off switching and sub-system isolation.
