Solid state relay 12V 40A with a semiconductor output.
It is controlled with a positive level via pins 15 / 31 (these can be swapped over, the opposite pin must be connected to ground).
Properties: The output can be used bi-directionally and ground disconnection is possible. The relay is not short-circuit proof. No switching noise. Insensitive to vibration and suitable for high switching cycles.
For controlling inductive loads. Typical applications: Controlling lamps, fans, blowers and all other applications with high switching cycles.
