Product Description
HART MTL4541 MTL Safety Barrier Repeater Power Supply
Product Overview
The MTLx541 provides a fully-floating DC supply for energizing a conventional 2- or 3-wire 4/20mA transmitter located in a hazardous area, while repeating the current in another floating circuit to drive a safe-area load. For HART 2-wire transmitters, the unit enables bi-directional communication signals superimposed on the 4/20mA loop current.
Key Features
- Single-channel design for reliable operation
- Supports HART communication (terminals 1 & 2 only)
- Green LED power indicator for clear status monitoring
- Safe-area circuit ripple < 50µA peak-to-peak
- Low temperature drift < 0.8µA/°C
- Suitable for Zone 0, IIC, T4-6 hazardous areas when certified
