H08RC
| Series | Temperature Module |
| Input type | 8 thermal resistance |
| COM Port | Built-in 1*RS485 |
| Remote I/O module | Supported |
| 8 channels thermal resistance input, A/D hardware conversion accuracy: 16 bits; Support various types of signals: Pt100, Pt1000, Cu50, Cu100. 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 24VDC 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 24VDC supply. | |
