MTL4544AS MTL5544A/AS CURRENT REPEATER
The MTLx544A provides an input for separately powered 4/20mA transmitters and also allows bi–directional transmission of HART
communication signals superimposed on the 4/20mA loop current, so that the transmitter can be interrogated either from the operator
station or by a hand-held communicator (HHC). Alternatively, the MTLx544AS acts as a current sink for a safe-area connection rather
than driving a current into the load.
Eaton’s latest generation of MTL IS interfaces utilises an innovative “One-Core” technology to ensure the highest quality and availability while
maintaining maximum flexibility at lowest cost. Incorporating advanced circuit design, a common set of components and innovative isolating
transformer construction, they achieve a significant reduction in power consumption while increasing channel packing densities. The compact,
16mm wide design reduces weight and gives exceptionally high packing density. They build on the proven success of the MTL2000, 3000, 4000
and 5000 range to bring the benefits of new developments in galvanic isolation without compromising the reliability of the designs from which
they have evolved.
The backplane mounting MTL4500 range is designed with system vendors in mind for “project-focussed” applications such as Distributed
Control System (DCS), Emergency Shutdown Systems (ESD) and Fire and Gas monitoring (F&G).
MTL4549Y-1
The MTL5500 clips quickly onto DIN rail, so it is compatible with the industry-standard mounting system. Wiring is simplified by plug-in
safe- and hazardous-area connectors, and a power plug which accepts a power bus; it all leads to quicker insertion, fewer wiring errors and
trouble-free, tidier installations.
Line fault detection (LFD) facilities are provided across the range of I/O functions; on the switch/proximity detectors, the MTL4523/5523
solenoid/alarm drivers and the isolating drivers. Analogue input units such as the MTL4541/5541 provide line fault detection by repeating o/c
or s/c currents to the safe-area control system. Status LEDs, configuration switches and ports are located on the top
or side of individual modules, as appropriate, for easy access. Both ranges have been designed for compatiblity with earlier
models. The MTL4500 range provides plug-replacements for the earlier MTL4000 units, while the MTL5500 range can easily replace MTL5000
units. Each offer the latest in modern technology and efficiency without compromise.
In addition to their use in IS circuits, specific models within the MTL4500 and MTL5500 range have been assessed and approved
for use in Functional Safety applications. These have been verified under the certified Functional Safety Management (FSM) programme
implemented by our MTL product line.
