Sierra Radio Systems 20 Amp DC Power Relays

Sierra Radio Systems 20 Amp DC Power Relays feature Powerpole® Connectors for power in and out, and a 30 Amp relay for remotely switching the power to a device or a series of devices that all consume less than 20 amps. There is an LED to indicate the state of the relay. External connections for 12-volt power in, pull to ground for relay control and voltage measurements are provided via screw terminals. This relay is normally connected to the GPIO module and doesn't feature its own Device Control Network jack.

Some assembly is required for this kit. The main board comes assembled with the 8-pin connector, power relay, and LED indicator all soldered to the board. The user will have to solder in the power pole connectors, install the mounting plate and the DIN rail clips.

NOTE: While the relay is capable of switching up to 30 amps, the traces on the board are conservatively rated for 20 amps.
