This 4 Road/Channel Relay Module (with light coupling) 12V module meet the safety standard as control areas and load area have the isolation groove. Optical coupling isolation module. The triggering of 4 Road/Channel Relay module is reliable, more stable. The double FR–4 circuit board design,...
It is a 5V 1 Channel Without Light Coupling Relay. The relay normally open interface maximum load: AC 250V/10A, DC 30V/10A. It has a trigger current of 5mA, and module working voltage of DC 5V. Each channel of the module can be triggered by a jumper...
It can be controlled directly by microcontroller (raspberry pi, Arduino, 8051, avr, pic, dsp, arm, arm, msp430, ttl logic) Optically isolated relays protect your microcontroller from damage if the equipment being controlled fails 12v 2 channel relay interface board, each one needs 15 20ma
