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;

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 -: Connec the DC power supply negative

3, XM : trigger side of the public port (through this interface can choose high or low trigger).

4, X1-X2:

Trigger side, you can choose high or low trigger, trigger current only 0.1mA;

Select the high-level trigger: 3-32V for the effective high level voltage;

Select the low-level trigger: 0-2V for the effective low voltage;

Relay output:

1, NO1-NO2: relay normally open interface;

2, C0M1-COM2: relay common interface;
