4 Channel 24V Relay Module with Optocoupler 200K These are Carbon Film ResistorThis 24 Volts operated 4 Channel Relay Module is an interface board any controller like Arduino, AVR, PIC, ARM, etc., can control it using digital signals. This module is capable of handling high currents such as AC250V 10A or DC30V 10A. The digital outputs from controllers and processors control larger loads and devices such as DC motors, AC motors, and other AC and DC devices. It's a four channel relay module, which means it can control up to four
