G3MB-202P DC 5V Solid State Relay Module is used to control high voltages and currents with an Arduino or similar device. Silent operation, small size and reliable, low power switching are the main benefits of these devices. These devices are opt isolated for the protection of control circuitry. Features : 4-Channel Solid-State Relay Rated output load: 100V ~ 240V AC (50Hz/ 60Hz) 2A per channel Rated input power: 5V, 160mA (all channels ON) Triggered at Low level (or Active Low) Separate LEDs showing the status of each Solid-State Relay Input control signal: Low Signal (Solid-State Relay ON / CLOSE), 0V- 2V or GND High Signal (Solid-State Relay OFF / OPEN), 3.3V - 5.0V or leave it floating Dimension: 57mm x 55mm x 25mm Offer two types of input control terminals: Header pin and Terminal Block Specifications: Control Input Voltage: 5V – opt isolated Control Input Current: 50mA MAX (10mA typical) – do not exceed Load Voltage: up to 240V Load Current: up to 2A Package Include: 1 x SSR Solid State Relay SSR G3MB-202P
