The Eaton MTL5541AS Repeater (4/20mA) from the Crouse-Hinds Series is an advanced intrinsically safe repeater designed to interface with smart transmitters using a passive current-sink input. It supports bidirectional digital communication superimposed on the 4–20mA analog loop, making it ideal for HART and smart instrumentation systems.
This module ensures safe, isolated communication between hazardous-area field devices and safe-area control equipment. With a wide operating range of 20–35V DC and low power consumption of 1.3W max, it performs reliably in industrial and explosive environments.
The MTL5541AS carries extensive safety certifications, including ATEX, IECEx, FM, and North American approvals, allowing installation in demanding global sites from petrochemical plants to offshore platforms and mining zones. Its explosion-proof ratings such as [Ex ia Ga] IIC, [Ex ia Da] IIIC, and [Ex ia Ma] I highlight its suitability for hazardous locations (Zone 0, Zone 1, Zone 2, Div 1, Div 2).
