Checking for live stock

The Eaton MTL5544/RS is a high-integrity interface module designed for hazardous-area environments, offering a 2-channel repeater power supply with zener barrier protection. It supports 4-20 mA current-loop transmitters located in Zone 0/IIC hazardous areas and provides galvanically isolated safe-area outputs suitable for control systems, DCS modules, or PLCs. The device features ATEX and IECEx approval, DIN-rail mounting, and a 20–35 V DC supply input, making it ideal for process-control, oil & gas and industrial automation applications where intrinsic safety and signal integrity are critical.

Core Capabilities of the Eaton 2 Channel Zener Barrier, Repeater Power Supply

Dual independent channels allow two transmitter loops to be interfaced from one module.
Approved for hazardous areas (Zone 0/IIC) and safe-area output circuits to 28 V max.
Fully floating DC supply for 2-wire or 3-wire 4-20 mA (or HART) transmitters in hazardous zones.
Low power dissipation and compact DIN-rail form factor enable high-density installations.
Backward compatibility with legacy MTL 5000 series simplifies upgrades and spares planning.
LED status indicator for power/presence simplifies diagnostic checks on-site.

Engineered for Critical Industrial Signal Interfaces

The MTL5544/RS is purpose-built for environments where signal integrity and explosion-proof protection cannot be compromised. It provides galvanic isolation between the hazardous-area input loops and safe-area outputs, ensuring reliable transmission of 4-20 mA transmitter signals along with optional bi-directional HART communication on channel 1.

Product Use Cases

Repeater power supply for 4-20 mA transmitters located in hazardous zones (oil & gas, petrochemical, refining).
Interfaces between Zone 0/IIC field instrumentation and safe-area control/monitoring systems.
HART-capable loop transmission with safe-area output for digital communications on analogue current loops.
Signal isolation and barrier for distributed automation racks and DIN-rail cabinets.
Applications requiring dual‐channel support in a compact footprint to reduce cabinet width.
