PILZ Safety Relay PNOZ X10 Series

PILZ safety relay principle: PILZ safety relay is composed of iron core, coil, armature, contact reed and so on. As long as a fixed voltage is added to both ends of the coil, a fixed current will flow through the coil, resulting in electromagnetic effect. Under the action of electromagnetic force attraction, the armature will overcome the tension of the return spring and draw towards the core, thus driving the moving contact and static contact (normally open contact) to draw. When the coil power, electromagnetic suction also disappeared, the armature will return to the original position in the spring reaction force, so that the moving contact and the original static contact (normally closed contact) suction. This suction, release, so as to achieve the purpose of conduction in the circuit, cut off. For the "normally open, normally closed" contact of the relay, can be distinguished in this way: the relay coil is not energized when the static contact is disconnected, called "normally open contact"; A static
