Abstract
An improved relay actuating processor for a system that remotely control distributed electrical loads. The relay module is a part of a transceiver decoder that receives commands from a central controller for controlling the state of latching relays for controlling the power circuits of the loads. The improvements include: the use of a progressively variable pulse length relay actuation signal to shorten perceived response time; the provision of automatic power and reset detective and annunciation; a matrix arrangement for pulsing relays that minimizes the number of relay drivers required for a given number of relays to be controlled; utilizing a power clamp limiting circuit for protecting relay drivers from overcurrent; automatic verification of a control actuation command from the central controller; the use of an improved watch dog reset including AC coupling; warning (flicker) mode operation which provides a warning that lights in a given area will soon go off; and a multi-mode reset arrangement permitting the automatic testing of relays.
