Technical Parameters Category Specification Model MTL4841 Product Type HART Isolator / Two-Wire Signal Conditioner Input Signal 4-20 mA with superimposed HART digital signal. Output Signal 4-20 mA (isolated replica of the input) with superimposed HART signal. Power Supply Loop-Powered. Operates from the signal loop itself. Isolation Galvanic Isolation between input and output circuits. A typical rating is 1500 V AC. HART Signal Handling Transparently passes the HART FSK (Frequency Shift Keying) signal. Key Features Ground Loop Elimination Yes. Prevents stray ground currents from affecting the signal. Noise Suppression Provides common-mode noise rejection. Intrinsic Safety When used with an associated intrinsic safety barrier, it can be part of a loop for hazardous areas. Accuracy Typically ±0.1% of span (for the analog signal). Load Capacity The maximum output load is limited by the available loop supply voltage. Mounting Standard 35 mm DIN rail. Operating Temperature -20°C to +60°C
