3BSE056767R1 ABB CI871K01 Industrial Network Interface

Product Overview

The ABB CI871K01 (Part Number: 3BSE056767R1) functions as a high-performance PROFINET IO Interface Kit for ABB System 800xA and AC 800M process control architectures. This industrial communication package bridges processing units and decentralized field instruments. It allows AC 800M controllers to operate as native PROFINET IO controllers, transmitting deterministic data packets to distributed I/O blocks, variable speed drives, and intelligent electronic devices (IEDs).

We deliver this hardware assembly as 100% brand new, original, and factory-sealed. The complete kit includes the CI871 Communication Interface module alongside its matching TP867 interface baseplate, backed by our 12-month industrial hardware warranty.

Technical Specifications

Engineering Advantages

• Accelerates Distributed Device Control: The module processes Ethernet-based PROFINET protocols at 10/100 Mbps in full duplex mode. This dedicated speed loop feeds real-time digital field device data back to the primary AC 800M processor without creating data bus bottlenecks during high-density I/O polling.

• Survives Corrosive Chemical Vapor Atmospheres: ISA 71.04 G3-compliant conformal coating protects the interior multi-layer printed circuit boards. This chemical shielding blocks airborne sulfur, moisture, and chlorine vapors from oxidizing copper tracks in wastewater treatment facilities and petrochemical refineries.

• Permits Zero-Downtime Hot-Swapping: Built-in backplane power isolation circuits allow technicians to insert or remove the active CI871 interface module while the system runs live. This feature lets you swap components without halting neighboring automation tracks or dropping the host CEX-Bus network power supply.

• Eliminates External Network Hub Expenses: The underlying TP867 baseplate integrates a built-in dual-port RJ45 Ethernet switch matrix. This port pairing allows engineers to daisy-chain network lines directly from module to module inside the cabinet layer, saving physical rail space by skipping standalone Ethernet switch installations.

FAQs

• Which specific ABB controller variants accept the CI871K01 interface kit?

  The CI871K01 matches the hardware configuration and signaling of the ABB AC 800M controller series. It links directly with PM861, PM864, PM866, and PM891 processing models through the integrated side-attaching CEX-Bus system rail.

• What installation sequence prevents port misalignment or backplane faults?

  Mount the TP867 baseplate firmly onto the standard 35mm DIN rail first, locking it into position next to the controller module or existing CEX-Bus extensions. Slide the CI871 interface housing downward into the baseplate guides until the internal dual pin assemblies mesh completely into the backplane, then lock the retention latches.

• Does this module require independent external grounding straps inside the panel?

  No. The TP867 baseplate features built-in metallic grounding clips that snap directly onto the metal DIN rail frame. This mechanical connection establishes a low-impedance ground path that drains off electromagnetic noise automatically, provided you ground the DIN rail to the primary cabinet earth terminal block.
