Product Description Technical Download
Brief Introduction
Manufacturer Bently Nevada
Module/Order Number 07AI91 GJR5251600R0202
Description Advant Controller 31, Analog Input Unit
Country of origin USA
Dimension & Net Weight 12x14x8.5cm, 0.45kg
Packing Weight 2kg
Function & Application

The 07AI91 is an analog input module in ABB's Advant Controller 31 series, primarily used as a remote module on the CS31 system bus, electrically isolated from the rest of the module. The 07AI91 has 8 analog input channels, is powered by a 24V DC supply, and can be configured as temperature sensor inputs or voltage inputs. Its features include:

1. Channels can be configured in pairs for connecting the following temperature or voltage sensors (electrically isolated sensors only)

  • ±10 V / ±5 V / ±500 mV / ±50 mV
  • 4...20 mA (requires external 250 Ω resistor)
  • Pt100 / Pt1000 (with linearization function)
  • J, K and S type thermocouples (with linearization function)

2. The ±5V range can also be used to measure 0...20 mA, but requires an external 250 Ω resistor.

3. Input channel configuration and module address setting are accomplished via DIP switches.

 

07AI91 Front Panel Operating Elements

  1. 8 green LEDs for channel selection and diagnostics; 8 green LEDs to display the analog value of a channel.
  2. Diagnostic display information list.
  3. Red LEDs to display error messages.
  4. Test button.

ABB 07AI91 Analog Input Module

 

The 07AI91 analog input module provides various diagnostic functions and performs self-calibration on all channels. The red fault indicator LED will illuminate if any of the following errors occur:

  • Detecting open-circuit faults at Pt100/Pt1000 resistance thermometer or thermocouple connections.
  • Storing and providing this information (fault type and location) when needed.
  • Identifying internal module faults.
  • Identifying transmission errors.
Other Information

Applications

The ABB AC31 07AI91 analog input unit can flexibly handle multiple signals in a single module, making it particularly suitable for applications requiring the acquisition of data from different types of sensors. For example:

  • Multi-zone temperature monitoring. The 07AI91 module has built-in sensor linearization and cold junction compensation functions. By connecting to thermocouples and RTDs, it can monitor the temperature of multiple points such as reactors, high-temperature furnaces, and bearings in real time.
  • Process parameter monitoring. By connecting to transmitters that output standard 4-20mA or 0-10V signals, the 07AI91 module can monitor key parameters such as pipeline pressure, tank level, and medium flow rate in real time, providing crucial data for control loops such as PID regulation.
