Description

The MTL4544/S is a 2-channel repeater power supply designed to energize and interface with conventional or smart 2-wire or 3-wire 4/20mA or HART transmitters located in hazardous areas. It repeats the current to drive safe-area loads and supports bi-directional digital communication signals for smart transmitters. The MTL4544/S can also act as a current sink for safe-area connections.

Features

Dual Channels: Supports two transmitters simultaneously.
HART Communication: Bi-directional transmission over 4/20mA loop.
Hazardous Area Compatibility: Suitable for Zone 0, IIC, T4–6 hazardous areas.
Current Sink Capability: For safe-area connections (MTL4544S).
