BL118 data sheet - .PDF file.

Radiometrix has introduced the BL118 bidirectional control device, which uses a half-duplex radio transceiver to establish a two-way wireless link for remote-control applications including security and fire-alarm systems, radio-frequency remote-control systems, industrial controls and long-range telecontrol with narrow-band FM radios.

The radio link operates continuously, providing a valid communication link indication.

The BL118 board is used in pairs: a master/initiator and a slave/responder. The relays are activated when the state of the input on one board changes and vice-versa.

The basic BL118 has a single logic input (diode protected, with pull-up) and an 8A 240V mains-rated SPCO relay for NO/NC output. A four per cent duty cycle communication interchange occurs every two seconds.

Key information

  • The BL118 board is compatible with any Radiometrix BiM-pin-out module; the best power-versus-range performance with the BL118 is achieved using the VHF BiM1 module.
  • With a 10mW BiM1-173.225-10 module fitted, the average current consumption is 1mA (relay off), achieving an open-field range that exceeds 500m; this allows for a two-year operating life from D cells with a continuous data link.
  • Each unit consists of a 76 x 62mm board; a mounted radio module; output, input and support circuits; LED indicators; and the BL118 chip itself.
  • The system address is set on an eight-way DIP switch and an SMA/MCX connector is provided for the antenna.
  • I/O and power connection use 3.81mm-pitch two-part terminal blocks.
  • The company offers 5V and 12V versions, differing in the relay type fitted, and the basic board is easily further customised for specific applications.
