AIS810

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 AIS810 is an Analog Input Signal Conditioning Module (16 bit) supporting 2/4-wire devices and HART communications.

Features and benefits

  • Analog input for 2-wire or external powered 4-wire field devices
  • Signal range: 4...20 mA and 0...20 mA
  • Can be used in hazardous areas
  • Transmitter power current limited to 30 mA
  • 16 bit A/D converter resolution
  • Channel to channel galvanic isolation
  • Hardware filter, rise time 1ms
  • Software filter configurable through parameters
  • Protected against wrong wiring
  • Configurable software filter
  • Diagnostics:
    • Loop supervision (open circuit and short circuit)
    • Hardware error supervision
    • Communication supervision
    • Device malfunction low, underrange, overrange and device malfunction high detection
    • Internal power supervision
  • Support of HART field devices (up to HART application layer revision7):
    • HART Pass-Through
    • Cyclic read of up to two HART Device Variables
    • HART Device Validation
  • 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.
