Signal Conversion: 2-wire (μA→mV) long-distance transmission; 3-wire (V→V) short-distance transmission.
Compatible Sensors: IEPE, 4–20 mA loop-powered, CAxxx/CExxx piezoelectric accelerometers, IPC707/IQS9xx signal conditioners, etc.
Safety Certifications: Ex explosion-proof (Zone 2/Div 2, IIC T4); SIL 2 according to IEC 61508.
Electrical Specifications: Operating power 24 VDC (20–28 VDC); Power consumption **<3.1 W**; AC bandwidth DC–20 kHz (±0.5 dB), -3 dB cutoff approximately 30 kHz; SNR >80 dB.
Installation and Physical Configuration: DIN rail mounting; removable screw terminals; housing PA66 GF30, weighing approximately 140 g; operating temperature −20–70 °C.
Part Number Explanation: 244-127-000-017: Basic part number.
A1: Environmental rating (Ex explosion-proof, suitable for hazardous areas).
B02: Transfer function (1 V/mA, zero offset: 12 mA→7 V, 13 mA→8 V), for IPCxxx/VE210 current output.
Typical Applications
Suitable for scenarios requiring high isolation and resistance to ground noise, such as vibration monitoring of rotating machinery (steam turbines, compressors), chemical/oil and gas hazardous areas, ships, and energy equipment, supporting long-distance signal transmission and safety-related functions [19].
Procurement and Usage Tips
End-use information must be provided; export control is required.
Prioritize procurement through authorized channels to ensure certification and version compatibility.
Installation must comply with explosion-proof and safety regulations; hazardous areas require IP54 or higher protective enclosures.
