IDEC Solid State Relay RSSDN

IDEC Solid State Relay


The Model RSSDN Solid State Relay from IDEC is a photo-isolated solid state relay for HVAC applications and Building Automation Systems, BAS. The 4-32 volt DC input voltage allows the relay to be used on analog or digital outputs. The solid-state relays provide reliable switching and long-life operation. However, these relays require careful application because excessive temperature, high inrush currents, or induced currents can affect solid state relay operation.
