Engineering Advantages

• Flexible Source/Sink Capabilities: The F 6705 supports both source and sink operational modes. This versatility allows engineers to integrate the module with various field device power configurations without requiring external signal converters.

• Long-Distance Signal Integrity: This module drives current signals over cable distances up to 1,000 meters. High electric strength (250 V against Analog-GND) ensures stable signal transmission even in facilities with significant potential differences between grounding points.

• High-Resolution Process Control: The 12-bit resolution divides the output range into 4095 steps. This precision prevents "stepping" effects in valve positioning, ensuring smooth modulation and reducing mechanical wear on final control elements.

• Thermal and Electrical Resilience: The hardware maintains strict accuracy—within 0.2% at 25 °C and 0.4% across the full 0 to +60 °C range. This stability eliminates the need for frequent re-calibration in non-climate-controlled industrial environments.

• Efficient Rack Utilization: Occupying only 4 TE, the F 6705 maximizes I/O density. It solves the challenge of limited cabinet space, allowing for more control loops in a smaller hardware footprint.

FAQs

• What is the maximum allowable resistance for the output loop?

  The total burden (RB), including the internal resistance of the field device and the cable resistance, must stay at or below 550 Ohms. Exceeding this limit prevents the module from maintaining the full 20 mA output.

• Does the F 6705 provide protection against electrical surges?

  Yes. The module features an electric strength of 250 V against Analog-GND, which shields the sensitive internal logic from common-mode voltage spikes often found in industrial grounding systems.

• Can I use this module for high-precision valve positioning?

  Absolutely. The 12-bit resolution provides the fine-tuned control necessary for precise valve travel. This ensures that your process variables remain tightly controlled within the safety parameters.

• Does the unit ship with the required plug-in connectors?

  We supply the F 6705 as a 100% Brand New unit in original packaging. Please verify if your specific application requires additional specialized HIMA terminal blocks or if you are utilizing existing subrack connectors.
