The output of many circuits have an alarm signal which must be connected to a remote switching device. Or; sometimes you will have a kit to test which needs a relay connected to it. For this purpose; this kit is perfect. A 12 volt (coil) relay mounts on the PC board which includes a protective diode and terminal blocks. The terminal blocks make for fast; easy screw-connection of wires to the coil and to the contacts. If you prefer a different relay coil voltage; the boards are available separately. Either use Philmore TB132; TB133 terminals or solder to the board. Board accommodates any Philmore relay from 3V to 24V coils (all ten amp contacts).
