ABB 216GE61 Input auxiliary relay assembly
The ABB 216GE61 input auxiliary relay assembly is part of the REG216 digital generator protection module. It can accommodate up to 16 auxiliary relays, and its main role is to provide complete potential isolation for the digital input signal, ensure the accuracy and stability of the input signal, and prevent the impact of external electrical interference on the protection module.
This component works with other components in the REG216 digital generator protection module, such as output auxiliary relay assembly and trip auxiliary relay assembly, to realize the protection function of the generator together. For example, when the generator is abnormal, it can trigger the corresponding protection mechanism through the action of the auxiliary relay according to the received digital input signal, such as cutting off the circuit and sending an alarm signal.
