ABB ICST08A9 Analog Remote I/O Module

Technical Specifications

• Current Output Configuration: Factory-set to 4–20 mA, configurable in “active” or “passive” modes (except for devices designed for Ex Zone 1/Div. 1, where reconfiguration is not permitted post-order).
• Power Requirements:
  • For “active” mode: No external power supply is required for the current output.
  • For “passive” mode: An external power supply is necessary (similar to pressure and temperature transmitters).
• PROFIBUS PA Interface:
  • Conforms to Profile 3.01 (fieldbus standard PROFIBUS, EN 50170).
  • Supports bus address configuration via DIP switches, system tools, or PROFIBUS DP master class 2 (e.g., Asset Vision Basic).
  • Default bus address set to “126” during shipment; must be reset to a valid range (0–125) during startup.
• Address Setting:
  • DIP switch 8 is factory-set to OFF (address set via fieldbus).
  • Address can also be modified via menu using display board keys.
• Transmitter Signal: Designed according to IEC 61158-2.
• PROFIBUS PA ID Numbers:
  • Manufacturer-specific ID: 0x3430.
  • Alternative standard IDs: 0x9700 or 0x9740.

Functional Characteristics

• Flexible Signal Configuration: Supports both “active” and “passive” modes for current output, adapting to diverse application requirements.
• Robust Communication: Features a PROFIBUS PA interface for seamless integration into industrial networks, enabling reliable data exchange.
