ABB XK08F1-A3.0 1SBP260104R1001 Product Description

Overview

ABB XK08F1-A3.0 1SBP260104R1001 is a digital mixed I/O extension module for the ABB AC31 40/50 series PLC system. XK08F1-A3.0 denotes the hardware and firmware version, while 1SBP260104R1001 is the official ABB order part number. This module provides 4 digital inputs and 4 relay outputs to expand the signal acquisition and load control capacity of the AC31 controller, widely used as spare parts for industrial cabinet maintenance and retrofit.

Features

ABB XK08F1-A3.0 1SBP260104R1001 has 4×24 V DC digital sinking inputs and 4×relay output channels. Each relay contact is rated 2 A up to 230 V AC/DC, suitable for switching contactors, solenoid valves and indicator lamps. It connects to the AC31 CPU via the extension bus and supports cyclic data exchange with the main controller. Individual LED status indicators are fitted for each I/O channel to facilitate quick on-site troubleshooting. The module adopts a compact plastic housing with IP20 protection and is designed for standard 35 mm DIN rail mounting. It complies with IEC 61131-2 standards and offers reliable EMC noise immunity for factory environments.

Specs

Brand: ABB Model: XK08F1-A3.0 Part number: 1SBP260104R1001 Product series: AC31 40/50 Product category: Mixed digital I/O extension module Digital inputs: 4 channels, 24 V DC Digital outputs: 4 relay channels, 2 A @ 230 V AC/DC Mounting: 35 mm DIN rail (TH35-7.5) Protection: IP20 Operating temperature: 0℃ ~ +55℃ Storage temperature: -40℃ ~ +75℃ Weight: 0.22 kg Standard: IEC 61131-2

Principle

ABB XK08F1-A3.0 1SBP260104R1001 receives field switch signals via the 24 V DC input terminals and transmits channel status to the AC31 CPU over the extension bus. When the CPU sends an output command, the internal relay coil is energized and the contact switches to drive the corresponding field device. The LED indicators reflect real-time ON/OFF status of each input and output point for commissioning and fault checking.

Applications

ABB XK08F1-A3.0 1SBP260104R1001 is used for general discrete signal control. Typical applications include packaging machinery, conveyor systems, water treatment, building automation, and spare replacement for existing ABB AC31 PLC control cabinets.
