Product Description

DESCRIPTION:

• This is a LOW Level 5V 4-channel relay interface board, and each channel needs a 15-20mA driver current.
• It can be used to control various appliances and equipment with large current.
• It is equipped with high-current relays that work under AC250V 10A or DC30V 10A.
• It has a standard interface that can be controlled directly by microcontroller.
• This module is optically isolated from high voltage side for safety requirement and also prevent ground loop when interface to microcontroller.

SPECIFICATION:

• Maximum AC current and voltage : 10A 250VAC
• Maximum DC current and voltage : 10A 30VDC
• Relay long life can absorb 100000 times in a row
• Module with diode current protection, short response time
• Optocoupler isolation, good anti-interference
• Low level pull-in, high-level release. Pull the status indicator light, release the status indicator is off
• VCC for the system power, JD_VCC for the relay power. Plug in the jumper cap
• PCB Size: 76mm x 56mm /2.99″x 2.21″ (L×W)
