This is intrinsically safe barrier, which is giving me a hard time. I wired an input on sinking plc card (Koyo) to terminal #2.
I have 3 of these barriers. Now, when 1 sensor closes, all 3 inputs turn ON. There is only 3 terminals on the barrier and additional screw for GND. This screw touches DIN rail, which is separately grounded. PLC card is connected to 24VDC-
Any ideas?
