MTL4549 ISOLATING DRIVER Brand New with Good Discount 

two-channel, for 4–20mA, HART®

valve positioners with line fault detection

The MTL4549 accepts 4/20mA floating signals from safe-area controllers to drive 2 current/pressure converters (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. 

Process controllers with a readback facility can detect open or short circuits in the field wiring: if these occur, the current taken into the terminals

drops to a preset level. The MTL4549C and MTLx549Y are very similar to the MTLx549 except that they provide open circuit detection only (i.e. no short-circuit detection).
