Solid State DC Relay
Solid State DC Relay

  • Description
  • Reviews


This is a solid state DC relay for switching DC currents of up to 80 amperes at voltages from 5vdc to 220vdc.  A small red light indicates when it is on. 

These work like mechanical relays but without the contact life issues.  Control voltage from 3-32vdc causes it to connect the two terminals.  This control voltage draws less than 25 ma.  You could actually use a bare Arduino or Macchina output to switch voltage.

We use these to switch DC voltages to heating elements in place of a Tyco Kilovac contactor.  Used with the JLD612 temperature controller, there is really no life limit to the number of cycles using this device, nor contact wear from breaking currrent flows repeatedly.
