Module description:<br />1. The module uses genuine quality relay・ normally open interfaces Maximum load: AC 250V/10A・ DC 30V/10A;<br />2. Using SMD optocoupler isolation・ driving ability・ stable performance; trigger current 5mA;<br />3. The module Operating voltage 5V;<br />4. The module can be high or low by a jumper setting trigger;<br />5. Fault-tolerant design・ even if the control line is broken・ the relay will not operate;<br />6. The power indicator (green)・ the relay status indicator (red)<br />7. The interface design of human nature・ all interfaces are available through a direct connection terminal leads・ very convenient<br />8. Module size: 50mm*26mm*18.5mm (L*W*H)<br />9. Four mounting bolts holes・ diameter 3.1mm<br /><br />Module interface:<br />1. DC+: positive power supply (VCC)<br />2. DC-: negative power supply (GND)<br />3. IN: can be high or low level control relay<br /><br />Relay outputs:<br />1. NO: normally open relay interface<br />2. COM: Common Interface Relays<br />3. NC: normally closed relay interface<br /><br />High and low level trigger options:<br />It is low level trigger when jumper connect to LOW pin<br />It is high level trigger when jumper connect to HIGH pin<br /> <br />Package Contents:<br />1 x 1-Channel H/L Level Triger Optocoupler Relay Module
