Select I/O – AIS830

Select I/O is an Ethernet networked, single channel granular I/O system for the ABB Ability™ System 800xA automation platform. Select I/O helps decouple project tasks, minimizes the impact of late changes, and supports standardization of I/O cabinetry ensuring automation projects are delivered on time and under budget. A Signal Conditioning Module (SCM) performs the necessary signal conditioning and powering of the connected field device for one I/O channel.

The AIS830 is an Analog Input Signal Conditioning Module for temperature measurements via RTD/TC/mV.

Features and Benefits

  • Analog input for 2-wire, 3-wire, or 4-wire RTD input or TC input with cold Junction Compensation
  • Can be used in hazardous areas
  • 16 bit A/D converter resolution
  • Channel to channel galvanic isolation
  • Software filter configurable through parameters
  • Protected against wrong wiring
  • Configurable software filter
  • Diagnostics:
    • Loop supervision (open circuit and short circuit)
    • Communication supervision
    • Internal power supervision
  • Single loop granularity – each SCM handles a single channel
  • Supports hot swap
  • Mechanical locking slider which turns off field device power and/or output before removal
  • Field disconnect function which can galvanically separate the field loop wiring from the SCM during commissioning and maintenance
  • All SCMs have electronic current limitation
  • Mechanical keying to prevent insertion of wrong module type after commissioning
  • 24V DC powered through Modulebus
  • Configurable through parameters
  • LED indicators on the SCM indicate the operational state of the module.
