Description: High level effective solid state relay. The input control signals is the low level (0-2.5 V), the relay is off; while the input control signal is high level (3.3-5V), the relay is on. Suited for controlling larger voltages with project. Can be used to activate up to two seperate 240V AC. Allows you to build in device control, operating remote lights or triggering systems when the module is supplied the signal. The screw terminals are well labelled and definition of the units function is shown underneath. Specification: Size: Approx. 5.5 x 3.3 x 2.3cm Solid State Relay is a new kind of contactless switching device which is composed of all solid state electronic components. Compared with the electromagnetic relay, its reliability is more higher, with the features of non-contact, long service life, fast and less outside interference. The output control terminal of the keyestudio solid-state relay must be connected to the circuit, and its working current needs to be bigger than 50mA, so that the solid state relay can be disconnected normally. Package Includes: 1 Piece Solid State Relay Module
