What is an output terminal in relay protection
Relay outputs are wired to ROx or ROy. x and COM screw terminals and serve for switching two-states devices. The COM terminal (which can be shared by two relays) serves for connection of the switched voltage (and others) by the relay to the ROx, or. This description is only intended for the use of trained specialists in control and automation engineering who are familiar with the applicable national standards. It is essential that the documentation and the following notes and explanations are followed when installing and commissioning these. Construction is designed to prevent seeping of flux when soldering and cleaning fluid when cleaning. This type is hermetically sealed with ceramic and metal plating. No harmful gas or humidity will ever reach the. Outputs must be designed to handle more current than inputs, so although the wiring may be similar, there are some key differences and protection considerations. Relay outputs are mechanical contacts and solid state outputs may take the form of transistor or TTL logic (DC) and triac. An Interposing Relay (IPR) is an auxiliary relay used to electrically isolate and interface two dissimilar systems, such as a 24 V DC PLC output and a 230 V AC contactor or motor starter. -
