• Weight: Approximately 0.15 kg
• Terminal Connection: Spring-clamp terminal blocks (no screwdriver required)

Operating Principle:
The input signal (0–10 V DC) is first conditioned by an input amplifier with high input impedance (> 1 MΩ) to prevent loading of the field source. The conditioned signal is then converted to a digital representation by a 16-bit A/D converter. A digital isolation barrier (optical or transformer-based) transfers the digital data across the 1500 V AC isolation barrier to the output side. On the output side, a 16-bit D/A converter reconstructs the analog signal, which is then converted to a 4–20 mA current output by a precision voltage-to-current converter with Howland current pump topology. The triple isolation ensures that no electrical path exists between input, output, and power circuits.

Advantages & Highlights:

• Complete Ground Loop Elimination: Triple isolation breaks all ground loop paths — critical for multi-ground installations
• High Accuracy: ±0.1% of span — suitable for precision measurement applications
• Universal Power: 85–265 V AC/DC — works worldwide without transformer
• Fast Response: ≤ 10 ms — suitable for dynamic process signals

Applicable Industries:

• Industrial Automation (OEM Machines)
• Process Control (DCS/PLC Signal Conditioning)
• Building Automation (HVAC)
• Power Generation (Turbine/Generator Monitoring)
• Water & Wastewater
• Marine & Offshore

Installation Requirements:

• Mount on standard 35 mm DIN rail inside a control cabinet
• Connect input wiring to the input terminal block; connect output wiring to the output terminal block
• Ensure power supply voltage is within 85–265 V AC/DC range
• Maintain minimum 10 mm spacing between modules for heat dissipation
• Ground the DIN rail to the cabinet earth bus

Usage Precautions:

• Verify input signal range matches the configured type (0–10 V DC in this case) before energizing
• Do not exceed 30 V DC on the input terminals (even with isolation, transient protection has limits)
• Do not connect the input ground to the output ground — this defeats the isolation purpose
• Check LED status indicators (power: green; fault: red) after installation
• Do not operate in ambient temperatures below -10 °C or above +50 °C
