MTL 4500 Intrinsically Safe Isolators MTL4549Y
MTL4549/C/Y - MTL5549/Y ISOLATING DRIVER two-channel, for 4–20mA, HART® valve positioners with line fault detection The MTLx549 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).
