Analogue output modules
The analogue output (AO) modules accept 4/20mA floating signals from safe-area controllers to
drive current/pressure converters (or any other load up to 800Ω) in a hazardous area.
MTL5549/ MTL5549Y - Isolating Driver
Two channel, for 4/20mA HART® valve positioners with line-fault detection
The MTL5549 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 so that the device can be interrogated either from the operator station or by a hand-
held communicator. 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 MTL5549Y is very similar to the MTL5549 except that it provides open circuit detection only
(i.e. no short-circuit detection).
