Relay with potential-free contact for remote control of the 12 to 24 V DC power supply. The flexible configuration and low power consumption make relay a versatile control technology. The potential-free contact is galvanically isolated from the device's power supply circuit. It can be used in low-voltage and high-voltage networks. There is a bistable and a pulse mode. The relay can be connected to a power supply and a reserve battery at the same time to protect against power failure. - Pulse 1?255 seconds - Power supply from 7 to 24 V - Potential-free contact
