New arrival MTL4546 / MTL4546C / MTL4546Y ISOLATING DRIVER for 4–20mA HART® valve positioners with line fault detection barrier products in stock for sale at Sunup company.


MTL4546 / MTL4546C / MTL4546Y product description:

The MTLx546 accepts a 4/20mA floating signal from a safe-area controller to drive a current/pressure converter (or any other load up to 800Ω) in

a hazardous area. For HART valve positioners, the module also permits bi-directional transmission of digital communication signals. Processcontrollers with a readback facility can detect open or short circuits in the field wiring: if these occur, the current taken into the terminals dropsto a preset level. The MTL4546C and the MTLx546Y are very similar to the MTLx546 except that they provide open circuit detection only.
