Reed Relays 1NO/5000VDC/0.2/50W; Coil: 24VDC/1200Ohms
The maximum switching voltage of a relay is the maximum voltage that can be across the contacts whether the relay is open or closed. Operating a relay with high voltages present can cause arcing, and this in turn erodes the contacts and eventually degrades contact performance.
A coil spike suppression diode is a protection device across the contactor coil. Energizing the contactor coil creates a magnetic field that forces the solenoid arm to engage the contacts. When the contactor is turned off, the magnetic field collapses causing a back “voltage spike” that can damage the controller.
