| Series | Analog Module |
| AI/AO points | 4AI/4AO |
| COM Port | Built-in 1*RS485 |
| Remote I/O module | Supported |
| 4 channels analog input, 4 channels analog output, A/D hardware conversion accuracy: 12 bits; Support 6 types of signals:[4,20]mA、[0,20]mA、[1,5]V、[0,5]V、[0,10]V、[-10,10]V; It can be used as the extended module for any types of PLC host; With the RS485 communication port, it can also be used as remote IO; When a extended module hanging at the back of the host though the parallel bus, it can be powered by the inner 24VDC on the host; It must be powered by external 220VAC when capacity of the inner 24VDC power supply is insufficient; When the module was used as remote I/O through serial bus, it must be powered by external 220VAC supply. | |
