Product Description
The MTL4541 is a high-performance repeater power supply from Honeywell’s MTL4500 Series, specifically designed for intrinsically safe process control systems. It provides a fully floating DC supply to power conventional 2-wire or 3-wire 4–20 mA transmitters located in hazardous areas, while repeating the current signal to a safe-area load. This guarantees accurate and reliable signal transmission, maintaining compliance with stringent safety standards.
In addition to supporting standard analog signals, the MTL4541 accommodates HART® communication, enabling bi-directional digital signals to pass through the analog loop. Its compact DIN rail design ensures convenient installation in control panels, and LED indicators provide immediate visual confirmation of power and signal status. The device is widely used in oil & gas, chemical, and pharmaceutical industries, where hazardous-area compliance is critical.
