12-84-7000 VHF/UHF Relay Output Receiver

The 12-84-7000 is a scalable, high sensitivity paging receiver with serial connectivity and 4 controllable outputs.

  •  

    Using the 12-84 Relay Receiver, devices can be controlled remotely by sending commands from a portable or fixed location paging transmitter or wide area paging network to switch relays on or off.  It is available in two versions, a VHF 12-84-7150 and a UHF 12-84-7450.

    The unit receives and decodes a numeric or alphanumeric pager call.  If the received unit number matches the 12-84 unit number or group number, the relays are switched as commanded by the message.

    The receiver is supplied with two clean contact relays rated at 1A 24V DC operation. LED’s indicate receiver operation and the relays’ status. Two additional open collector outputs are also provided.

    Normally closed and normally open relay contacts are available and the relays can be individually programmed for latching or momentary operation.

    The 12-84 is an economic solution for basic remote control applications where only one or two switched outputs are required.

    Should a greater number of relays be required, this can be achieved using the Salcom 12-34 Relay Output Module which provides another four relays. This module can be “daisy chained” to allow any number of relays to be controlled.

    Network paging messages can be monitored on a PC (using  software such as Salcom’s VisualPET paging software) using an optional cable to connect the computer to the 12-84 programming connector.
