Working Principle:
The X20SO6300 receives digital values from the controller via the X20 bus. Each of the 6 channels contains an independent 16-bit D/A converter that transforms the digital input value into a proportional analog current signal. The output stage uses a precision current source circuit with feedback control to maintain accuracy across the full load range. Channel-to-channel galvanic isolation is achieved through optical or magnetic isolation barriers, ensuring that faults or noise on one channel do not affect other channels. The module supports both 2-wire (loop-powered) and 4-wire (externally powered) connections.

Advantages & Highlights:

• High precision 16-bit resolution for demanding process control
• True channel isolation eliminates cross-talk and ground loop problems
• Fast 1 ms update rate for dynamic control applications
• Wide load range (0–600 Ω) provides flexible field wiring options
• Comprehensive diagnostics reduce downtime and maintenance costs
• Software-configurable eliminates need for hardware jumper settings

Applicable Industries:

• Process automation (chemical, pharmaceutical)
• HVAC control systems
• Flow and pressure control
• Valve positioning systems
• Batch processing
• Water and wastewater treatment

Installation Requirements:

• Mount on DIN rail TS 35 (EN 60715)
• Connect to X20 system bus via front-facing connector
• Use shielded twisted-pair cables for analog outputs in noise-sensitive environments
• For 4–20 mA operation, ensure loop supply voltage ≥ 24 V DC
• Ground the shield at one end only to avoid ground loops
• Torque terminal screws to 0.8 Nm

Usage Precautions:

• Do not exceed 600 Ω total loop resistance per channel
• Do not apply voltage directly to current output terminals (current source)
• Verify output range configuration in software before commissioning
• Ensure proper bus power supply (24 V DC, min. 5 A recommended for full system)
• Do not disconnect output loads while the module is energized (may cause voltage spikes)
• Use shielded cables in electrically noisy environments
