Product Description
DC 12V 16 Channel Relays Module With Low Level Trigger Expansion Board
Module description 1. The module adopts genuine high-quality relay, normally open interface load: AC 250V/10A, DC 30V/10A;
2.Using industry-quality isolated optocoupler, with strong anti-interference ability and stable performance; the trigger current isonly 3mA;
3. The working voltage of the module is 5V, 12V, and you can choose; there are 1, 2, 4, 8, and 12 modules to choosefrom; the default is 12v, if you need 5v, please contact customer service. Thank you
4. Low-level pull-in; the module contains acurrent-limiting resistor, which can be directlycontrolled by the positive and negative poles of the power supply, or controlled by the I/O port of the single-chip microcomputer;
5. Power indicator, 16 relay status indicators
6. The interface design is humanized, all interfaces can be directly connected through the terminal block, which is very convenient
7. There are 4 fixingbolt holes for easy installation
