Description
This 4 channel relay module uses a 30A relay with optocoupler isolation on each channel for stable, interference-resistant switching. It is powered by DC low voltage only (5V, 12V or 24V options; this version is 5V) and must not be connected to mains supply. High or low level trigger is selected with a jumper. Maximum load of the open interface is AC250V/30A or DC30V/30A, with a trigger current of 5mA. Each channel has an LED indicator. Suitable for PLC automation, industrial control, IoT control and home intelligence projects.
