4 channel relay module contains four 5V relays and the associated switching and isolating components, which makes interfacing with a microcontroller or sensor easy with minimum components and connections. The contacts on each relay are specified for 250VAC and 30VDC and 10A in each case, as marked on the body of the relays.
Supply voltage – 3.75V to 6V Trigger current – 5mA Current when the relay is active - ~70mA (single), ~300mA (all four) Relay maximum contact voltage – 250VAC, 30VDC Relay maximum current – 10A
