Input and output wiping relays for time-dependent control systems
Machines and systems such as dosing systems and rinsing systems are where wiping relays are used. DOLD wiping relays are available as both input as well as output wiping relays. While the input wiping relays immediately switch the operating voltage to the work position after installation, output wiping relays are placed over the voltage control contact on the control input. If this is open, the relay immediately switches to the work position. Both relay types switch back to resting position immediately after the expiration of the set wiping time.
