I/O Circuit and Wiring diagrams
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
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 |
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) |

I/O circuit diagram
| Note: |
If a capacitive load is directly connected to the output, malfunction may occur. |
