Abstract

A method for operating a fail-safe programmable solid-state relay, the method comprising the steps of performing a set of self-tests at an initial start-up and cyclically during the powered state of the solid-state relay, wherein a self-test comprises continuously detecting and comparing a state of the at least one switch with an expected state therefor and wherein if any self-test within the set detects an unexpected state, substantially simultaneously therewith a failure flag is set in a non-volatile memory and the at least one switching circuits are set to a safe or default state; setting an integrity flag and an integrity count flag within the memory when all self-tests in the set are passed; and reading the failure flag from the memory at any subsequent start-up, wherein if the failure flag is not set, the integrity count flag is read and a set of self-tests is performed.
