ABB 1SBP260101R1001 Remote IO Extension Module

ABB 1SBP260101R1001 Remote IO Extension Module—XO08R1-B4.0—is an eight-relay output extension for ABB Advant Controller 31 (AC31) and Advant OCS systems that connects to the CS31 system bus to expand digital outputs from a central controller. It provides eight binary relay outputs switching at 24 V DC, enabling remote control of connected loads across the CS31 network. Designed as a centrally extensible remote IO unit within ABB’s Advant architecture, the module measures roughly 4.0 in x 3.0 in x 4.0 in (10.2 cm x 7.6 cm x 10.2 cm). The part number 1SBP260101R1001 corresponds to the XO08R1-B4.0 variant, confirming eight relay outputs on this extension module. Compatible ABB AC31 controllers or Advant OCS systems can use it to scale IO, providing a straightforward means to distribute relay control across a plant floor via the CS31 bus.
