07AI91

Overview

The 07AI91 is a J = Fe-CuNi 0...1200 °C iron / copper-nickel + = Fe - = CuNi from ABB. It is part of ABB's industrial automation product portfolio.

Application & Technical Notes

As a j = fe-cuni 0...1200 °c iron / copper-nickel + = fe - = cuni, the 07AI91 is intended for deployment in panel-based control cabinets and machine enclosures where the ABB product portfolio equipment is installed. It performs a defined automation function within the control system and is selected to match the installed ABB platform.

Key published characteristics include a 24 V DC rating. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.

Maintenance & Diagnostics

Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.

Sourcing & Procurement

When sourcing the 07AI91, distinguish three supply tiers: (1) genuine ABB stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.

Confirm mechanical and electrical compatibility with your ABB product portfolio installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Frequently Asked Questions

Specifications

ABB Analog Input Module 07 AI 91 8 inputs, configurable for temperature sensors or as voltage inputs, 24 V DC, CS31 system bus The analog input module 07 AI 91 is used as a remote module at the CS31 system bus. It has 8 analog input channels with the following features: • The channels can be configured in pairs for the connection of the following temperature or voltage sensors: • ± 10 V / ± 5 V / ± 500 mV / ± 50 mV • 4...20 mA (with external 250 Ω resistor ) • Pt100 / Pt1000 with linearization • Thermocouples types J, K and S with linearization • Only electrically isolated sensors may be used. • The range of ± 5 V can also be used for measuring 0..20 mA with an additional external 250 Ω resistor. • The configuration of the input channels as well as the setting of the module address are performed with the DIL switches. The 07 AI 91 uses one module address (group number) in the word input range. Each of the 8 channels use 16 bits. The unit is powered with 24 V DC. The CS31 system bus connection is electrically isolated from the rest of the unit. The module offers a number of diagnosis functions (see chapter "Diagnosis and displays"). The diagnosis functions perform a self-calibration for all channels. Displays and operating elements on the front panel 1 8 green LEDs for channel selection and diagnosis, 8 green LEDs for analog value display of one channel 2 List of diagnosis information relating to the LEDs, when used for diagnosis display 3 Red LED for error messages 4 Test button
