XVS-440-10MPI-1-10 EATON

Product Dimensions：

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).

These models have been assessed for use in IEC 61508 functional safety applications. 

SIL2 capable for a single device (HFT=0) 

SIL3 capable for multiple devices in safety 

redundant configurations (HFT=1)
