Dear all,
I want your help in below issue:
I have blowdown valve on compressor skid and when i close it(energize solenoid)
Find valve take no action. I measure the voltage on plc terminal(DO) found 24v.but when i connect solenoid and measured from solenoid side (the other side of terminal block) found no voltage.uptill now i wondered from this case as i remove solenoid cable the 24 voltage returned back.i have allenbradely control logix and 1756-OB32 is the digital output card.i try to connect 24v direct, the solenoid is enegized normally. I want to know what is the problem...
