The R-OR-0008M module is functionally fully consistent with the C-OR-0008M module (identical inputs, outputs). The only difference is in communication. The module is in a wireless version – a periphery module of the RFox network.
It is powered from a 24 VDC supply (similarly to the C-OR-0008M module).
The label C-OR-0008M shows an SMA connector for external antenna, which is also in the R-OR-0008M module.
