Dual DC Solid State Relay with EFM Processor and Dual RS232 Interfaces

  • 1995


Description:

 

This module contains Dual CPC1002N DC Solid State Relays. A Solid State Relay (SSR) is a voltage controlled switch. It lets you control a big voltage with a little voltage. Think of a light switch. Your finger turns the light on by mechanically moving the switch so that the big voltage can go to the light. With a solid state relay a low voltage of less than 2 volts can control a high voltage like 240 volts. A light switch isolates the high voltage from your finger, the SSR isolates the high voltage from the low voltage control signal. This lets you control a high voltage device from a microcontroller.

This relay is a low voltage relay used for DC current applications.

It also contains an EFM32ZG108 Gecko low power microcontroller and two RS232 serial ports allowing it to be daisy chained in a network. Pre-Programmed for use in an openHAB Home Automation system or can be Re-Programmed for other uses.
