MTL4546Y Isolating Driver, for 4–20mA HART® valve positioners with line fault detection, MTL 4500 Intrinsically Safe Isolators. The MTL4546 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. 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 MTL4546C and the MTL4546Y are very similar to the MTLx546 except that they provide open circuit detection only (i.e. no short-circuit detection).
