What is the use of Interposing relay,
Is it only required for solenoid Valves because of different requirement Voltage (PLC is restricted to 0.5A at 220 VAC, but the solenoid which is to be connected to the relay requires 1.2A at 220 VAC.)
Can/Why we use it for Analog Signals .
How it works in the whole operation , in brief ? .I know its very basic. If any one can help me out of this .
Thanks in advance !!
