Two Arduino Solid State Relay (Red)

2 solid relay module (red)
Product introduction:
1， solid state relay omron 5 v， 240 v / 2 a， output resistance fuse with 240 v / 2 a.
2， size: 55 * 25 * 33 (length * width * height)
3， input power supply: 5 VDC
4， input control signal voltage:
Status (0-2.5 V low level relay ON)
State high level (3-5 v relay OFF)
Module interface:
Input part:
The positive (DC + : connect power according to the relay voltage power supply)
DC - : connect power negative
CH1: relay module (effective) low level trigger signal trigger end
CH2: relay module (effective) low level trigger signal trigger end
High level and low level meaning:
High level refers to the trigger signal trigger terminal (CH) and power between the cathode with a forward voltage， usually with the power of the positive connection way of a trigger and trigger the end， when the trigger side has the positive voltage or to trigger voltage when the relay is off.
Low level trigger refers to signal triggering end of OV， between the cathode voltage or trigger voltage lower than the power of the anode voltage， low enough to trigger voltage， the relay， absorption is usually connect the power of the cathode and trigger the end of a trigger mode， make the relay is off.
Electrical parameters:
Current trigger voltage trigger current voltage static current work
1 road 5 v 12.5 5 v 2 0 12.5 mA mA mA
2 road 5 v 12.5 5 v 2 0 12.5 mA mA mA
Product use:
1. The module of power supply: power supply must be dc， voltage to the relay
2. The connection method: when signal trigger side has low level trigger relay will get through， have electricity equipment and work.
