ABB XC32L2-B4.0 1SBP260111R1001 AC31 Combined Digital Input/Output Module, 16DI+16DO

Overview The ABB XC32L2-B4.0 (1SBP260111R1001) is a mixed digital input and output module for ABB AC31 Advant Controller 31, communicating via the CS31 fieldbus. It integrates 16 digital input channels and 16 digital output channels, widely stocked as spare for legacy water treatment, packaging and power plant automation systems.

Features This XC32L2 module supports screw terminal wiring and individual channel LED status indication. The XC32L2-B4.0 1SBP260111R1001 is plug-in slave type, compatible with AC31 master CPU, and supports on-site configuration of switch status signals. It provides built-in signal isolation and communication watchdog protection.

Specs Model: XC32L2-B4.0, Part No.:1SBP260111R1001 Series: ABB AC31 Advant Controller 31 Type: Combined digital I/O module Channels: 16 DI + 16 DO Signal: 24VDC Bus: CS31 fieldbus Mounting: DIN rail Protection class: IP20 Certifications: CE Product status: obsolete industrial automation spare

Principle The XC32L2-B4.0 collects discrete switch signals from field sensors and limit switches, transmits data to the AC31 master controller, and executes switching commands from the CPU to drive relays and actuators. It reports channel failure and bus communication faults.

Applications The XC32L2-B4.0 1SBP260111R1001 is widely used in thermal power auxiliary control cabinets, water treatment plants and packaging production lines. It serves as remote mixed digital I/O for AC31 distributed control systems.
