Overview
The Allen-Bradley 700-SH25GZ24 solid state relay is a hockey puck-style optocoupler-isolated switching device designed for industrial automation, motor control, and HVAC systems. With specifications of 3–32 V DC input, optocoupler isolation, 25 A @ 24–265 V AC output, zero cross switching, and LED status indication, this Series A relay provides contactless switching with no moving parts, resulting in extended service life and reduced maintenance.
