Often system designers need the ability to communicate STOP and other control commands wirelessly from a machine to a control station, or machine to machine. Standard telemetry systems are unsuitable for the task because they lack the redundancy, self-monitoring, and fail-to-safe design required. The KTC system provides for the transmission of up to 20 commands + Category-3 STOP from one location to another. Conveniently DIN-rail mounting, the system easily integrates with PLCs or conventional control panels.
