Technical Specifications / Parameters Parameter Specification Manufacturer Type Code 6197/15-101-500 UD/S 4.600.2 Product Family / Series ABB Instrumentation / Transducers (UD Series or similar) Device Type Electronic Voltage Transducer / Signal Converter / Isolator Primary Function To provide galvanic isolation and conversion of an AC voltage input to a proportional DC analog output signal. Input (Measured Variable) AC Voltage Input Voltage Range (Nominal) 500V AC (Likely the nominal or maximum input voltage, e.g., 0-500V AC). Input Frequency Typically 50/60 Hz. Output Signal Standard Analog Output, most commonly: • 4...20 mA DC (two-wire loop powered) 或 • 0...10 V DC (three-wire, with separate supply). (The suffix 4.600.2 often indicates a specific output type and scaling.) Power Supply Depends on output type: • For 4-20mA two-wire: Loop powered (16-30V DC typically). • For 0-10V three-wire: Requires external auxiliary supply (e.g., 24V DC, 110/230V AC). Accuracy High accuracy, typically ±0.2% or better of full scale. Isolation Galvanic isolation between input, output, and power supply circuits (typically 2-4 kV). This protects connected equipment from transients and ground loops. Mounting DIN Rail Mounting (35mm). Connection Screw-clamp terminals. Operating Temperature Typically -20°C to +70°C. Response Time < 250 ms. Standards & Approvals IEC/EN 61010-1 (Safety), IEC/EN 61326 (EMC), CE, UL, cUL. Typical Applications • Main voltage monitoring in switchgear and control panels. • Generator output voltage measurement. • Busbar voltage feedback for automatic voltage regulators (AVRs). • Power quality monitoring systems. • Any process requiring a safe, accurate, and isolated representation of an AC voltage for control or logging.
