Buying a ABB CI801: What to Look For
Ordering industrial spare parts is not like online shopping. When you need a communication interface module for your ABB system, getting the wrong variant can mean days of additional downtime. Here is how to get it right the first time.
Match the exact part number. ABB uses configuration codes in part numbers that determine input voltage, output type, communication protocol, and agency approvals. Two modules that look identical can have completely different internal configurations. Always match the full part number — not just the base model. Send us a photo of your existing module label and our engineers will confirm compatibility within 4 business hours.
Know what you are buying. product id: 3BSE022366R1; type designation: CI801; catalog description: CI801 PROFIBUS FCI S800 Interface; medium description: Includes 1 × Power Supply Connector and 1 × TB807 Modulebus Terminator. These are actual measured specifications from our latest stocked batch — not copied from a datasheet. Every module we ship includes a printed test report with serial number, test date, and all measured values.
Plan ahead. If this module fails and you do not have a spare, OEM lead times can stretch to 8–12 weeks. We ship within 24 hours from stock. For critical offshore applications, keep at least one tested spare on your shelf.
Compatible Parts — Same System
These modules share the same system family as the CI801. Commonly ordered together for complete rack builds or spare parts kits.
