The G3VM relays improved temperature performance permits the design of more densely packed boards. In practice, for testing applications this can allow more tests to be carried out simultaneously, and ...

Unlike traditional automation systems that only offer ON/OFF control through relays, this project takes a step ahead ... or even future sensors like motion detectors, temperature sensors, or LDRs.

Output options include Relay, 0-20mA, 0-10V, and 12VDC/30mA SSR drive, making it suitable for devices. For systems requiring data communication, an RS485 module supports Modbus RTU. Built for ...

By that measure, it’ll be hard to top [Robert]’s latest hack which uses the controller board from an everyday oscillating fan to build a three-way remote-controlled relay board. Most ...
