905 U -X

  • The ELPRO 905U 1/2/3/4 –( Operating Frequency 865- 867 MHz)wireless I/O range is easy to use and simple to install.

 

  • The modules are completely integrated,  including micro controller, input/output (I/O) circuits, radio transceiver, RS485/232 serial port and power supply with battery backup facilities.
  • Each module is housed in an industrial strength extruded aluminum case, with plug-in terminal strips for ease of wiring connection and maintenance.
  • The 905U modules provide a wireless radio link for discrete (switch contact), pulse/counter and analog signals. The 905U also has a RS485 multidrop serial port, for communications to I/O expansion modules.
