Frequently asked questions

• How many channels does the ABB IMFAI02 support?
  The module provides 8 differential analog inputs for 4-20mA or 0-10V signals.
• What is the update rate for each channel?
  We sample each channel at 100 Hz, giving 10 ms response time per channel.
• Can I mix current and voltage inputs on one module?
  Yes, you can configure each channel individually for current or voltage.
• What software supports this module?
  ABB Control Builder and 800xA systems fully support the IMFAI02 module.
• Does this module provide isolation between channels?
  We use common isolation (1500 Vrms) between field and logic, not per channel.
• What cable type do you recommend?
  We recommend shielded twisted-pair cable, 20-22 AWG, with proper shield termination.
• How do I mount the module?
  We design the ABB IMFAI02 for 35 mm DIN rail mounting in a control cabinet.
