Installation Guidelines

  • Ensure the control system is powered down before installing or removing the module from the backplane.
  • Handle the module using ESD-safe practices to prevent damage to sensitive internal electronics.
  • Ensure proper seating in the I/O rack and secure the module using the integrated locking mechanisms.
  • Use shielded twisted-pair cabling for analog signals to minimize EMI/RFI interference in industrial environments.
  • Verify that the field wiring matches the terminal assignment for the specific connection method (pressure clamp or dedicated cable).

FAQ

Does the AAI135-S00 support HART communication?

Yes, this module supports HART communication, allowing for the transmission of digital data alongside the analog 4-20 mA signal for device diagnostics and configuration.

What is the isolation rating of this module?

The module features 500 V AC withstanding voltage between input channels and between the input and the system, ensuring high signal integrity and protection against ground loops.
