AXIS 223M - Unit Connectors 51
I/O Terminal connector pinout table
Pin | Function | Description |
1 | Output A | On the external device output terminals (A and B), there is no distinction |
|
| between positive and negative (+ and |
2 | Output B | |
|
| pler and are electrically isolated from the other internal circuitry. |
|
| The maximum load should not exceed 100mA and the maximum voltage |
|
| should be not more than 50VDC or 35VAC. |
|
|
|
3 | Digital Input 1- Photocoupler Anode (+) | Photocoupled Input 1. Electrically isolated from the chassis and connec- |
|
| tors, this input can be supplied from an external DC voltage or the DC |
4 | Digital Input 1 - Photocoupler Cathode | |
|
| Power Input/Output on pins 9 (DC+) and 10 (GND). |
|
|
|
5 | Digital Input 2 - Photocoupler Anode (+) | Photocoupled Input 2. As above. |
|
|
|
6 | Digital Input 2 - Photocoupler Cathode |
|
|
|
|
7 | A | |
|
|
|
8 |
|
|
|
|
|
9 | DC + Power Output | This can drive the photocoupler inputs or other equipment. The output |
|
| voltage level is 3.0 V. A maximum current of 100mA can be sourced from |
|
| the DC output. |
|
|
|
10 | GND | Ground. |
