High-Low Trigger 12VDC 1 Channel Relay Module with Optocoupler
Price in Sri Lanka

Specification:

• The module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A.
• Using SMD optocoupler isolation, driving ability, stable performance; trigger current mA.
• The module voltage: 12V
• The module can be set to high or low triggered by jumper.
• Fault-tolerant design, even if the control line is broken, the relay will not operate
• The power indicator (green), relay status indicator (red).
• Interface design humane, all interfaces can be connected directly via terminal wiring leads, very convenient.
• Module size: 50mm * 26mm * 18.5mm (L* W* H)
• Set four mounting bolts holes, hole 3.1mm, 4.5mm * 20.5mm pitch.
• Designed for 12V battery design, when the battery voltage below (10V) automatically cut off the output load,
• timely prevent the battery over discharge, damage the battery, (self consuming about 80 MA) Note: automatically
• disconnects the load after, when the battery voltage is their own rise to set values above is not switched on again,
• load, need to manually start

Module interface:

• DC +: Connect with positive power supply
• DC-: Connect with negative power.
• IN: Can be high or low level control relay.
• Relay output:
• NO: Normally open relay interface, the relay before the vacant after the pull shorted with COM
• COM: Common Interface Relay.
• NC: Normally closed relay interface relay shorted with COM ago, after the pull-vacant
• High and low level trigger selection ends:
• When jumper short circuit with LOW is low lever trigger.
• When jumper short circuit with high is high lever trigger.

Technical parameters:

• Quiescent current: 5mA
• Maximum current: 80mA
• Trigger current: 2-4mA
• Trigger voltage(low): 0-4V
• Trigger voltage(high): 4.5-12V
