This is a 1-Form-C (Single-Pole, Double-Throw) relay that is operated by 5 or 28 volts from any Linc or other source. It may be used to control any device that may be controlled by a remote switch closure, or may be modified to do so. Use it to control projectors, event-mark data being gathered by another system, or to operate other stimuli which do not operate on 5 VDC or 28 VDC. If the device is operated 110 volts A.C., use the A29-19 below.

A 25-foot control cable is supplied with the controller.
