Emerson’s TopWorx TV-LED Switchbox provides a local, ultra-bright LED position indicator plus an electrical signal/digital input that communicates valve position remotely to the control room or plant management system. With its 360° viewing angle, the device enables visual indication of a valve’s position at night, in low light, or from long distances to improve plant safety. It is to accept other internal switch options such as reed and mechanical switches and can be ordered for monitor-only applications or with an integrated solenoid valve for on/off valve control. Operating temperature recommendations range from -58° F (-50° C) to 140° F (60° C).
