P-line web sensor with PoE for measuring temperature and relative humidity, with a flood detector and binary inputs for biphase signals.
The P8653 web sensor is designed to measure temperature or relative humidity with up to two external probes. This allows values to be measured from two different points with a single device.
The device has three binary inputs. The P8653 has a dedicated first binary input for connecting the LD-81 flood detector (included).
The other two binary inputs allow the connection of dry contacts or binary sensors with voltage output.
Communication with the device is via the Ethernet network. The P8653 can be powered by an external power supply or Power over Ethernet (PoE).
