Feature:
1, DC 5-32V wide voltage power supply, with anti-reverse power supply capacity;
2, the output rated load: AC / DC 0-50V / 2A; Maximum load: AC / DC 0-60V / 3A (within 100ms);
3, the output port is normally open type of switch contacts, the contact is not charged node, the current direction without requirements;
4, the input control high and low selectable; built-in current limiting resistor, you can directly use the power of the positive or negative control, you can also use the microcontroller I / O port control;
5, the module anti-interference ability, stable performance; trigger current minimum 0.1mA;
6, with power indicator (red) and each way relay status indicator (blue)
7, the use of blue terminals;
8, module size: 6.0cm * 5.0m * 1.0cm (L * W * H)

Precautions:
This module can be used directly for signal or resistive load control;
If you are using control for inductive loads (eg small motors, solenoid valves, etc.), keep more than 3 times the remaining amount and add freewheeling diodes at both ends of the inductive load.

Module interface
Module Control:
1, DC +: Connect the DC power supply positive；
2, DC -: Connect the DC power supply negative；
3, X1-X4:
Relay control interface, high-level (3V) relay pull, low-levl (less than 2V) relay disconnect, trigger current only 0.1mA. Relay output:
1, NO1-NO4: relay normally open interface;
2, C0M1-COM4: relay common interface;

Package Included:
1*4-Channel Solid State Relay Module
