4. Product Introduction (Anti-Template)
The ABB 07AC91 is a remote analog input/output module designed for the Advant Controller 31 (AC31) system operating on the CS31 bus. It provides 16 analog channels that can be configured in two primary operating modes.
In 12-bit mode the module offers eight independently configurable analog inputs and eight analog outputs, supporting signal ranges such as ±10 V or 0…20 mA. In 8-bit mode the 16 channels can be assigned in pairs as either inputs or outputs with reduced resolution. Configuration is performed via DIL switches. The module is powered by 24 V DC and communicates with the central controller over the electrically isolated CS31 system bus. It is commonly used for process measurement and control signals in distributed Advant OCS installations.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm type designation (07AC91), Product ID (e.g., GJR5252300R0101), DIL switch settings, and connector condition. Photograph all labels.
- Functional Testing – Apply 24 V DC, verify CS31 bus recognition, and check basic analog channel operation where a test system is available.
- QA & Packaging – Protect the terminals and connectors, clean the module, and pack in anti-static protective packaging.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial I/O modules. Packaging must protect against electrostatic discharge and mechanical shock; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
Operating Mode Selection – DIL switch settings determine 8-bit or 12-bit mode and channel assignment. Incorrect settings cause incorrect signal scaling or channel mapping.
Signal Type Matching – Ensure field wiring matches the selected voltage or current range. Mixing ranges without reconfiguration leads to measurement errors.
CS31 Bus Addressing – The module occupies input and output words on the bus. Address conflicts with other modules will prevent proper communication.
Power Supply – Maintain stable 24 V DC within the specified range. Undervoltage or excessive ripple can cause analog inaccuracy or module faults.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified 07AC91?
As a mature Advant Controller 31 module, availability depends on surplus stock. Typical lead time after verification is 5–15 business days plus standard shipping.
What is the function of the 07AC91?
It is a configurable analog input/output module for the system bus used with Advant Controller 31.
How many analog channels does it have?
16 channels that can be configured as inputs or outputs depending on the selected operating mode.
What signal ranges are supported?
Common ranges include ±10 V, 0…10 V, 0…20 mA and 4…20 mA.
What is the common Product ID?
GJR5252300R0101 (other variants such as GJR5252300R3101 also exist).
Is it still in active production?
It is a legacy Advant Controller 31 module and is primarily available through surplus and specialist channels.
What should be confirmed before ordering a replacement?
Exact type designation (07AC91), Product ID, required operating mode (8-bit or 12-bit), and compatibility with the existing bus configuration.
