Do printing plants need to install relay protection
You should use external electromechanical devices, such as relays or limit switches, that are independent of the PLC system to provide protection for any part of the system that may cause personal injury or damage. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. The protection relays are normally provided for different. Relion protection and control relays for several application reduce complexity. The relays are in round glass cases.

The first requirement for relay protection devices is
The various protective functions available on a given relay are denoted by standard. For example, a relay including function 51 would be a timed overcurrent protective relay. An overcurrent relay is a type of protective relay which operates when the load current exceeds a pickup value. It is of two types: instantaneous over current (IOC) relay and definite time overcurrent (DTOC) relay.
