4 Relay Module Schematic. It is equiped with high current relays that work under ac250v 10a or dc30v 10a. This is a 5v 4 channel relay interface board and each channel needs a 15 20ma driver current.
The usb to serial chip ft232rl helps to upload sketches quickly to the board. It can be used to control various appliances and equipment with large current. The contacts on each relay are specified for 250vac and 30vdc and 10a in each case as marked on the body of the relays.
In this circuit we have designed an isolated pcb for 4 relays.
The other side has three low voltage pins ground vcc and signal which connect to the arduino. In this circuit we have designed an isolated pcb for 4 relays. The contacts on each relay are specified for 250vac and 30vdc and 10a in each case as marked on the body of the relays. Numato lab s 4 channel programmable relay module is a feature rich product that can be programmed with arduino ide.
