Description
With the heavy duty terminals these 5 Volt activated relays are perfect for high draw electronics like wiper motors and lights. The relays are powered by a 5 Volt power supply and the sense pins can be connected directly to a digital pin(s) of an Arduino, there is a sense pin for each relay on the dual relay board. The relays can also be activated by connecting 5 Volts to the appropriate sense pin.
The sense pins can be set to detect either a low signal or a high signal by simply moving the jumper pin. On the dual relay board there there is a jumper for each relay
- The module uses genuine high quality 30A relay, normally open interface maximum load: AC 250V / 30A, DC 30V / 30A.
- The use of SMD optocoupler isolation provides a strong drive capability with stable performance;
- Trigger current is 5mA.
- The module can be set by a jumper for either high or low triggering.
- Module Size: 72mm * 40mm * 24mm (L * W * H), weight: 46g.
- Four mounting holes: 3.1mm, spacing 44.5mm * 27.5mm
Relay power parameters:
Minimum current: 5mA
Maximum current: 190mA
Sense/Trigger current: 2-4mA
Module terminal description:
1. DC +: 5 Volt positive
2. DC-: Ground or Negative
3. IN: signal trigger terminal (the default trigger voltage and power supply the same)
4. High / low level trigger mode jumper selection is: Jumper set Low for Low signal activation, Jumper set High for High signal activation.
5. Normally closed (NC): normally closed relay
6. Common (COM): Relay Common
7. Normally open (NO): relay normally open
