|
The AX-RHT-SM is a range of Room Relative Humidity & Temperature transmitters with Modbus RTU output. An integrated LCD display is available as an option. Wiring is simplified with connections all made on the back-plate,and a plug-in electronics housing. Communication parameters can be configured locally using dipswitches or over the network.Options for this range of sensors include the addition of various passive temperature sensors for most BMS systems. |
