Relay Board

Numato Lab® RL40001

We use these Relay Boards from Numato Lab® for controlling lights, larger relay-contactors, and similar powered devices. The relay board is wired to a ROS computer with a USB cable, and appears in the computer's /dev directory as a serial device. We have developed a ROS driver using Numato's API, so we can control the relays through rosservices, and monitor the GPIO inputs through rostopics.
