Description:
This 1 channel 5V 30A relay control board module with optocoupler modules is compliant with international safety standards, control and load areas isolation trenches it has a single relay a genuine.
The inputs of 5V 30A Relay Module are isolated to protect any delicate control circuitry. It can be used as a single chip module for appliance control and work with both DC or AC signals where you can control the 220V AC load.
Specifications:
- Channel: 1
- Trigger Voltage: 5VDC
- Switching Voltage: 250VAC@30A
- Switching Voltage: 30VDC@30A
Features:
- High impedance controller pin
- Pull-down circuit for the avoidance of malfunction
- One normally closed contact and one normally open contact
- Triode drive, increasing relay coil
- Power supply indicator lamp
- Control indicator lamp
- With 4 fixed screw holes, hole diameter 3.1mm, convenient installation, and fixation
Pin Descriptions:
- DC +: DC power supply positive;
- DC -: DC power supply module negative;
- IN: Signal input terminal(support High/Low Level switch freely);
- Normally open (NO): Relay normally open;
- Common terminal (COM): Relay common;
- Normally closed terminal (NC): relay normally closed terminal
Note:
On the high level and low level-triggered mode, friends who do not understand, have a look:
- High-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered a way.
- Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understood as a signal input terminal and the GND negative electrode short circuit triggered isa way 1-channel relay module connection.
Package Included:
1 x 1 Channel 5V 30A Relay Control Module Isolated Relay Control Board For High Power Applications With Optocoupler
