GX-□U(B)

DC 2-wire type

I/O circuit diagram

GX-□U(B) I/O circuit diagram
Note: The maximum load current varies depending on the ambient temperature.
Symbols・・・ ZD: Surge absorption zener diode
Tr : PNP output transistor

Wiring diagram

GX-□U(B) Wiring diagram

Conditions for the load

1) The load should not be actuated by the leakage current (0.8 mA) in the OFF state.
2) The load should be actuated by (supply voltage – 3 V) in the ON state.
3) The current in the ON state should be between 3 to 70 mA DC.
[In case the current is less than 3 mA, connect a bleeder resistance in parallel to the load so that a current of 3 mA, or more, flows.]

GX-□U(B)-J GX-F□U-J

Spatter-resistant of DC 2-wire type

GX-□U(B)-J GX-F□U-J I/O circuit diagram

Notes:

1) This is when the mating cable CN-22G-C□ is connected. The connecter pins No.2 and No.4 are short-circuited inside the mating cable connecter. However, when the mating cable CN-24-C□ is connected;
GX-□U-J (normally open): (Black / 4) 0 V
GX-□UB-J (normally closed): (White / 2) 0 V
2) The maximum load current varies depending on the ambient temperature.
