Isolated 24VAC/DC Solid-State Relay Reference Design

PMP12072

Design files

Overview

This isolated, bi-directional, solid-state switch can control current flow into both AC and DC loads. Rated for 24VAC, it can switch loads up to approximately 1Arms/4Apeak.

Features
  • 24VAC/DC solid state relay replaces mechanical relay
  • Board size is approximately 35mm x 12mm
  • Controls current flow into both AC and DC loads
  • Higher current rating possible by simply replacing FETs
