ABSTRACT:
An intelligent voting node for a multiple node, fault tolerant, distributed intelligence control system having a plurality of optically isolated relays for connecting a power source to a load device and providing total optical isolation for processors of the voting node from faults occurring in the power source. The voting node includes triple redundant two-out-of-three voters each coupled to one of three redundant digital communication and control processors within the node. Built-in-self-test capability using optically isolated receiver devices provides for avoidance of latent failures.
