Product Description
The MTL4544 is a SMART transmitter repeater power supply from the MTL4500 Series, specifically engineered for use in hazardous areas. This device powers and repeats the analog current signal from 2-wire or 3-wire transmitters, transmitting the signal to the safe area. It also supports bi-directional HART communication, enabling the transparent passage of digital diagnostics and configuration data.
Ideal for process automation systems, such as Distributed Control Systems (DCS) and Safety Instrumented Systems (SIS), the MTL4544 features 3-port isolation for enhanced signal integrity and safety. It is DIN rail mountable and certified for use in Zone 0 hazardous areas, ensuring reliable performance in challenging industrial environments. The MTL4544 guarantees compliance with ATEX, IECEx, FM, and CSA standards, making it a perfect choice for high-risk process control systems.
