Abstract

A system and method is provided for testing industrial control modules. Input and output stimulus signals, communication lines, measurement device lines and relay contacts are provided at a tester interface panel. This allows for a test developer to configure the relay contacts in any way that the developer desires to provide appropriate connections of stimulus, communications and measurements for a given industrial control module. The switching of the relays between a normally closed position and a normally open position can be controlled by output modules coupled to a computer. The relays can be insertable and releasable in a socket for easy fault isolation and replacement. Furthermore, the same relays or similar relays can be employed for both low current measurements and high power stimulus.
