07 AC 91
ABB
Overview
The 07 AC 91 is an automation component from ABB. It is part of ABB's industrial automation product portfolio.
Application & Technical Notes
As an automation component, the 07 AC 91 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 07 AC 91, 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.

Specifications
ABB Analog Input/Output Module 07 AC 91 16 inputs/outputs, configurable for ±10 V, 0...10 V, 0...20 mA, 8/12 bit resolution, 2 operating modes, CS31 system bus Intended purpose The analog input/output module 07 AC 91 is used as a remote module on the CS31 system bus. It contains 16 analog input/output channels that can be configured in two operating modes: • Operating mode "12 bits": 8 input channels, individually configurable ±10 V or 0...20 mA, 12 bit resolution plus 8 output channels, individually configurable ±10 V or 0...20 mA, 12 bit resolution • Operating mode "8 bits": 16 channels, configurable in pairs as inputs or outputs, 0...10 V oder 0...20 mA, 8 bit resolution • The configuration is set with DIL switches. • The PLC offers an interconnection element ANAI4_20 for measuring signals of 4...20 mA (refer to 907 PC 331, connection element library). The module 07 AC 91 uses up to eight input words on the CS31 system bus plus up to eight output words. In the operating mode "8 bits", 2 analog values are packed into one word. The operating voltage of the unit is 24 V DC. The CS31 system bus connection is electrically isolated from the rest of the module..
