Control relays

A selection of electronic modules and relays to compliment the access control systems. For easy interfacing, most outputs are isolated relay contacts. Functions include toggling and timers. All are bare circuit boards.


503 handy relay

Two pole relay (N/O and N/C contacts) with selectable energising voltages from 12 to 24V ac/dc.


504 delayed handy relay

Two pole relay (N/O and N/C contacts) with a fixed time delay before energising.


120 opto isolator relay

Optical relay with a solid state N/O output. Input 12-24V ac/dc. Used to trigger control panel inputs such as electric gate controllers.


509-D toggle relay

Two pole relay (N/O and N/C contacts) with toggle input. The relay changes state on each pulse of the same input.


122 regulator & relay

A 2 function module. A voltage reducer gives a 12Vdc regulated output from a 15V to 24V input. Also, includes a single pole relay (N/O and N/C contacts).
