MTL4546/C/Y – MTL5546/YIsolating Driver for 4–20mA HART® Valve Positioners with Line Fault Detection
The MTLx546 series 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 permits bi-directional transmission of digital communication signals. Process controllers with a readback facility can detect open or short circuits in the field wiring, indicated by a drop in current taken into the terminals. The MTL4546C and MTLx546Y models provide open circuit detection only, omitting short-circuit detection.
