This 12V 16 channel relay interface board is used to control various appliances and equipment that require a large current. This module consists of a 5V relay module with a light coupling LM2596 power supply. These modules are controlled directly by the microcontrollers such as Arduino, 8051, AVR, ARM, DSP, MS430, TTL logic easily. In order to function this 16 channel relay interface board each relay requires a 15-20mA driver current. The indication of LED shows the relay status and standard interface controlled directly by the microcontrollers. The 12v electromechanical relay module with an AC contact capacity of 250v has light coupling protection for isolation of control circuitry. The plate load power module doesn’t need any external power supply. This module also supports all SCM drive. In this module, each relay can be ON/OFF by an opto isolated input that can be controlled by a microcontroller output pin.
This module is also used to control various applications and equipment with a large current compliant with international safety. Moreover, this module is used as a microcontroller development board and also as appliance control, PLC extended output. The relay terminal Common(C), normally open (NO), normally closed NC) accessed through the screw terminals thus making wiring much easier. Each relay common terminal “COM” are independent, user-friendly access to different signals. And each relay remains normally closed and normally open with the port. And also each relay is equipped with motion lights.
