IMPROVED SWITCHBOX POSITION VISIBILITY FOR GREATER PLANT SAFETY
THE TOPWORX TV- LED Switchbox option featuring what is claimed to be the industry’s first ultra- bright, easy-to- see light- emitting diodes (LEDs) for highly visible position indication, has been released by Emerson. These products are visible at long distances and can be used in hazardous locations where switchbox position indication is required, says the manufacturer.
The 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 TopWorx TV- LED Switchbox enables visual indication cation of a valve’s position at night, in low light, ht, or from long distances to improve plant nt safety,” said Leandru Schiau, senior product oduct manager at Emerson Automation Solutions tions for TopWorx Switchbox. “In addition, it is the only switchbox on the market that allows valve integrators to combine LED position indication with the TopWorx GO Switch proximity sensor to create a highly reliable and durable valve monitoring solution.” Emerson says it has designed the TopWorx TV- LED Switchbox with the flexibility to accept other internal switch options such as reed and mechanical switches. The device can be ordered for monitor monitor- only applications or with an integrated solenoid valve for on/off valve control.
With its intrinsically- safe and nonincendive approvals, along with a wide operating temperature range of - 50° C to 60° C, the TopWorx TV- LED Switchbox is ideal for both general and extreme applications in the process industries, promises Emerson.
