H16DI
| Series | Digital Module |
| DI/DO points | 16DI |
| COM Port | Built-in 1*RS485 |
| Remote I/O module | Supported |
| 16 channels digital input, can be used as the extension module for any types of PLC host; With the RS485 communication, it can also be used as remote IO; When a extension module hanging at the back of the host through the parallel bus, it can be powered by the inner 24VDC on the host; It must be powered by external 24VDC when capacity of the inner 24VDC supply is insufficient; When the module was used as remote I/O through serial bus, it must be powered by external 24VDC supply. | |
