Synopsis

Simple SPST switching for high-power (up to 30A) loads

 

Full Description

The Solid-State Relay is a universal direct replacement for any relay-based SPST switching device rated for 30 amperes or less. While this project does not include normally-closed contacts, the vast majority of relay applications in the context of a vehicle only use the normally-open contacts even if the relay is constructed in a SPDT configuration. The universal design of this project allows its use with high-side or low-side switching, and the operating safety margin is well in excess of the standard fusing currents in use in all but a very few relay applications.

Design Goals

This project includes the following design goals in addition to, or in substitution of, the standard project design rules for Initiative projects:

• Relay coil leads must not be polarity-specific.
• N.O. contacts must not be polarity-specific. Bidirectional switching is required.
• Relay's coil and switched sides must be isolated.
• Current safety margin must exceed 2:1 (60A minimum).
• In addition to surviving load dumps, switched side must survive significant back-EM spikes from breaking current flow through inductive loads.
