Universal Signal Converter, 1 Analogue Output, RS-485 is a DIN-rail signal converter designed to scale and isolate field signals for PLC, SCADA and instrumentation systems. Universal inputs, galvanic isolation and Modbus RTU communication support flexible process integration.
🔧 Technical Highlights:
- Inputs: DC voltage, DC current, RTD, thermocouple, resistance and potentiometer signals
- Analogue output: configurable current and voltage ranges including 0-20 mA, 4-20 mA, 0-10 V and 2-10 V
- Communication: RS-485 Modbus RTU on terminals 13 and 14
- Display: 3-digit LED display with keypad programming
- Supply: 85-253 V AC
- Auxiliary output: 16-25 V DC, 23 mA for 2-wire and 3-wire transmitters
- Isolation: galvanic isolation between supply, input, analogue output and RS-485
- Environment: -10 to +60°C operating, 0-95% RH non-condensing
✅ Benefits:
- Converts multiple sensor and transmitter signals to standard analogue outputs.
- Helps prevent ground-loop issues through galvanic isolation.
- Speeds commissioning with local display and keypad setup.
- Saves panel space with a narrow DIN-rail housing.
- Supports fine tuning through 20-point linear calibration.
🚀 Applications:
- Factory automation signal conditioning
- Energy, water and process skids
- Oil, gas and marine instrumentation panels
- Food, beverage and pharmaceutical process control
Designed for stable isolated signal conversion in industrial automation and process systems.
