Description:

12V relay contact capacity 10A 250V, with optocoupler protection. Onboard power supply module does not need an external power supply. I / O port driver is active low.
Used as a microcontroller development board module can be used as appliance control, can be used as PLC extended output.

Module features:
Control signal voltage range: trigger signal is low 0-2V; high voltage must not exceed 5V.
Using the industry's top-quality isolation optocouplers, anti-interference ability, stable performance; trigger current is only 3mA.
1-16 can be any full on / off, or any road.
Output Type: AC 220V 10A or directly connected to DC30V 10A load.
Each relay common terminal COM are independent, user-friendly access to different signals, each relay are normally closed and normally open with the port.
Each relay is equipped with motion lights, pull off, off off.
Interface design humane, all interfaces are available through the terminal directly connected leads, very convenient.
Has four mounting bolts holes for easy installation.
PCB board size: 180MM (L) * 90MM (W) * 20MM (H)

Electrical parameters:
Supply voltage: 5V 12V (DC)
Supply Current: more than 200mA
Each relay can load: 250V 10A (AC) or 30V 10A (DC)

Note:
Power supply to meet the range DC 12V;
Power requirements according to wiring diagram, is not reversed;
Product LM2596S slight chip buck fever is a normal phenomenon, relays, long working hours have a normal fever phenomenon, are normal;
Load power to give leave a margin relay load should avoid high-power (about 2000W) and long working environment, there will be some impact on the life of the product.

Most current-measuring devices such as our current panel meter are only good for low side measuring. That means that unless you want to get a battery involved, you have to stick the measurement resistor between the target ground and true ground. This can cause problems with circuits since electronics tend to not like it when the ground references change and move with varying current draw. This chip is much smarter - it can handle high side current measuring, up to +26VDC, even though it is powered with 3 or 5V. It will also report back that high side voltage, which is great for tracking battery life or solar panels.

A precision amplifier measures the voltage across the 0.1 ohms, 1% sense resistor. Since the amplifier maximum, input difference is ±320mV this means it can measure up to ±3.2 Amps. With the internal 12 bit ADC, the resolution at ±3.2A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is ±400mA and the resolution is 0.1mA. Advanced hackers can remove the 0.1-ohm current sense resistor and replace it with their own to change the range (say a 0.01 ohm to measure up 32 Amps with a resolution of 8mA)

We include a 6-pin header (so you can easily attach this sensor to a breadboard) as well as a 3.5mm terminal plug so you can easily attach and detach your load. Usage is simple. Power the sensor itself with 3 to 5VDC and connect the two I2C pins up to your microcontroller. Then connect your target power supply to VIN+ and the load to ground to VIN-. We have an Arduino library right now that will do all the gain, range, and math for you - just plug and go! We'll have a more detailed tutorial up shortly.
