Where is the EUCHNER safety relay used?
The Anstron safety relay is designed for the safety circuit that controls the input of the contactor, etc., with the input confirming the safety of the machine and confirming the safety.

Requirements for safety circuits
1. When the emergency stop is released, the machine cannot suddenly restart.
2. In case of failure of the machine safety circuit, the machine power supply can be stopped.
3. When the safety circuit fails, the machine can no longer be started.
If the security switch, light curtain, etc. confirm the safe input, the above functions cannot be achieved. Then, how can the safety circuit be implemented? When the dual circuit can be doubled, it is impossible.
Dualization is necessary, but in addition to this, the dual circuit is checked against each other to confirm that all safety circuits have been disconnected once, and if necessary, the operator can start the conditions. Also, from another point of view, when the input switch wiring is short-circuited or the possibility of grounding due to breakage of the wire sheath, the sudden start of the machine must be prevented.
In fact, in order to facilitate the construction of the safety circuit, the safety relay and other components are combined, and the basic emergency stop circuit and the safety circuit are called the safety relay module.

Where is the EUCHNER safety relay used? EUCHNER safety relay KCB1E002B000000W: The Essence Euchner safety relay is used to assign signals generated by safety switches, emergency stop buttons and emergency control units, and for dangerous machine functions. Reliable stop. The compact housing (22.5mm), DIN standard mounting slot, and application options up to EN 954-1 for safety control class 4 make this safety relay convincing.
