8 Relay Module is a simple and convenient way to interface 8 relays for switching application in your project. Input voltage level supports TTL as well as CMOS. Easy interface with Microcontrollers based projects and analogue circuits.
Ideal for interface between High Current Robotics and low power microprocessors.
Interfaces with Arduino, BBC Micro:bit, Raspberry.
The module has anti-interference ability, trigger current is only 1mA. Each input has integral suppression diodes for inductive loads & a peak load current rating of 600mA (500mA continuous) and can withstand at least 50V in the off state. The module has built-in current limiting resistor can be used directly with positive voltage control, you can also use the microcontroller I / O control.
