1 Channel Relay Module 5V High and Low Level Trigger Relay Control

This Relay Board Maximum load: AC 250V/10A, DC 30V/10A With power and relay action indicator. each relay has normally open and normally closed contact. Can be selected by jumper relay and TTL or ground.

These Relay Boards use photocoupler isolation that has strong driving ability and stable performance. The isolation circuit prevents damage to I / O port by relay switch current. The module has a jumper so you can set rather the unit state changes with high or low signal. Has screw terminals for relay (NC,C, NO) and for input; Coil +, coil – and trigger.

Using SMD optocoupler isolation, strong driving capability, and stable performance. Fault-tolerant design, even if the control line is broken, the relay will not operate; And interface design is humanized, all the interfaces can be directly connected through the terminal lead, so convenient. Wide Application This 5V relay board works well with Arduino/ARM /PIC /AVR /MCU/Raspberry/CNC machine/ PS4 etc.

Power Interface：
DC +: positive power supply (voltage by relay requirements, 5V.9V.12V and 24V selection)
DC-: negative one
IN: can be high or low-level control relay

Load Interface:
NO: normally open relay interfaces, relay before hanging, pull back and COM short-circuited
COM: Relay Common Interface
NC: normally closed relay interfaces, relay and COM short-circuited before, and after the pull-vacant
