Peel magnetic relay - the application and current situation analysis of solid state relays
Applications for Solid State Relays
(1) The recommended value of the foreign SSR trigger signal (i.e., the current through the light-emitting tube) is 10mA DC, and the recommended value of the domestic SSR trigger signal is 12-25mA DC.
(2) Multiple SSRs can use the same trigger signal, which is common in the control of three-phase AC loads.

Peel magnetic relays – the characteristics and working principle of relays
When the input quantity (such as voltage, current, temperature, etc.) reaches the specified value, the electrical appliances that make the output circuit to be controlled on or off can be divided into two categories: electrical quantity (such as current, voltage, frequency, power, etc.) relays and non-electric (such as temperature, pressure, speed, etc.) relays.

Wiring method of relay - Peel magnetic relay
1. Control wiring: You think of it as a DC relay. 3. 7 is used to connect to 12V control voltage; 2. 7 is used to connect to 24V control voltage. In the meantime, 7 is used as the negative electrode of direct current, and it is connected to the neutral line when used. 2. Connect to the front of 220V.
Second, the operation control: although the control voltage is connected ...

Peel magnetic relays – testing of relays
(1) Measure the resistance of the contact: use the resistance of the multimeter to measure the resistance of the normally closed contact and the moving point, and the resistance value should be 0; The resistance between the normally open contact and the moving point is infinite. From this, it is possible to distinguish which is a normally closed contact and which is normally open.
(2) Coil resistance: multimeter R...

Common faults of Pilz safety relays with contacts and how to deal with them
The most common ones are the following:
(1) Contact failure
1. The phenomenon that cannot be disconnected due to mechanical occlusion of the contact (the needle-like protrusion formed on the contact and the pit biting each other), fusion welding, or cold welding.
2. Due to the contact resistance becoming large and unstable, the circuit cannot be normal ...

REPAIR OF PILZ SAFETY RELAYS
AS MENTIONED EARLIER, PILZ SAFETY RELAYS ARE THE MAIN COMPONENTS FOR CONTROL CIRCUITS AND MONITORING AND PROTECTION SYSTEMS FOR ELECTRIC LOCOMOTIVES. When the locomotive is running, when the motor, electrical appliances or connection lines in the main circuit and auxiliary circuit fail, the fault can be replaced by the Pilz safety relay of the corresponding monitoring and protection system.

The working principle and characteristics of Pilz safety relays
Pilz safety relays generally consist of an iron core, a coil, an armature, a contact reed, etc. As long as a certain voltage is added to both ends of the coil, a certain current will flow through the coil, resulting in an electromagnetic effect. Under the action of electromagnetic attraction, the armature overcomes the pulling force of the return spring and sucks in the iron ...
