Abstract
A plurality of power driver modules are removably mounted on a circuit board which interfaces with a computer control system. The input/power driver output switches in each module use optical coupling. A controller sets the power switches according to instructions from the computer control system, and the system can determine the set state of the power switches by reading a set state memory or directly determining the actual state of the switches by reading the switch state from an input circuit on the input/output power driver module.
