Pololu Basic SPDT Relay Carrier with 12VDC Relay (Assembled)

Description: The Pololu basic relay carrier modules make it easy to control a single-pole, double-throw (SPDT) switch from low-voltage, low-current control signals. The modules are available with 5 V and 12 V power relays—Omron G5LE-14-DC5 and G5LE-14-DC12, respectively.

The carrier board routes the three relay control pins to 0.1″-spaced pins compatible with standard solderless breadboads and female servo cable connectors. The assembled version of this board has a 0.1″ straight male header soldered to these pins while the partial kit version includes 8×1 straight and right angle 0.1″ male header strips that can optionally be broken into 3×1 pieces and soldered in. The relay switch pins are routed to a set of large pads intended for use with a 3-pin 5mm-pitch terminal block and a set of smaller pads with a 0.2″ pitch, making them compatible with 0.1″ perfboards. The assembled version of this board has a terminal block soldered to these pins while the partial kit version includes a 3-pin terminal block that can be optionally soldered in. The carrier board has four mounting holes that work with #2 or M2 screws.
