SSR-40DD Solid State Relay

This is DC To DC SSR-50DD Solid State Relay Module 3-32VDC/5-200VDC 40A. A solid-state relay (SSR) is an electronic switch, which, unlike an electromechanical relay, contains no moving parts. The types of SSR are photo-coupled SSR, transformer-coupled SSR, and hybrid SSR. A photo-coupled SSR is controlled by a low voltage signal which is isolated optically from the load.

The control signal in a photo-coupled SSR typically energizes an LED which activates a photo-sensitive diode. The diode turns on a back-to-back thyristor, silicon-controlled rectifier, or MOSFET transistor to switch the load.

This particular SSR can switch current loads of up to 10A with a 5-200VDC input and a zero cross trigger control method. Each one of these relays is equipped with four screw terminals (for use with ring or fork connectors) and a plastic cover that slides over the top of the relay to protect the terminals.


  1. Long service life and high reliability
  2. Reduced electromagnetic interference
  3. Highly reliable, compact size designed to offer users maximum simplicity
