8 Channel SSR Solid State Relay Module 250V 2A – for 3.3V and 5V control voltage
FREE Canada & USA shipping available (see details)
A Solid State Relay SSR switches voltage just like a mechanical relay with coil and contacts, but without coil and contacts! An SSR doesn’t contain any electro-mechanical components and uses semiconductor technology to switch AC or DC current (depending on the type).
This module comes with 8 separate channels, each channel can switch AC of up to 250V with 2A.
A power supply 5V DC is required, with an output current of 100mA or more. Please connect the DC power supply to the DC+ and DC- pins on the board.
Channel control inputs are marked with CH1 to CH8 and require a control voltage of 3.3 to 5V DC (logic level).
High-Current relay modules (30A) are available as well.
