Detailed Product Description

MTL4546/c/Y – MTL5546/Y
ISOLATING DRIVER
for 4–20mA HART® valve positioners 
with line fault detection

The MTLx546 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 MTLx546Y are very similar
to the MTLx546 except that they provide open circuit detection only  
(i.e. no short-circuit detection).
