1 channel 5V relay module Trigger

Description : 5V 1 Channel Relay Module Low level for SCM Household Appliance Control For arduino DIY Starter Kit • The module uses genuine quality relay, normally open interfaces • Using SMD optocoupler isolation, driving ability, stable performance • The module can be high or low by a jumper setting trigger • Fault-tolerant design, even if the control line is broken, the relay will not operate • The power indicator (green), the relay status indicator (red) • The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient • Maximum load: AC 250V/10A, DC 30V/10A • Trigger current: 5mA • Working voltage: 5V • Module size: 50 x 26 x 18.5mm (L x W x H) • Four mounting bolts holes, diameter 3.1mm • DC+: positive power supply (VCC) • DC-: negative power supply (GND) • IN: can be high or low level control relay • NO: normally open relay interface • COM: Common Interface Relays • NC: normally closed relay interface • It is low level trigger when jumper connect to LOW pin • It is high level trigger when jumper connect to HIGH pin
