ABB 1SBP260025R1001 Advant Controller 31 Basic Unit

This basic unit serves as the core controller for ABB Advant Controller 31 systems. It executes user programs and manages all connected I/O modules efficiently. Therefore, this component delivers reliable performance for industrial automation applications.

Physical Dimensions and Weight Specifications

The ABB 1SBP260025R1001 features a compact metal housing for rack mounting. Its width occupies a single slot in the Advant chassis. The unit depth measures 250 mm for backplane connectivity. Consequently, technicians can install this controller without special tools.

Interface Types and Connection Layout

The ABB 1SBP260025R1001 provides one RS-232 port for programming access. A second RS-485 interface supports fieldbus communication with I/O racks. The front panel carries a 9-pin D-sub connector for diagnostic tools. Hence, users can monitor system status without opening the cabinet.

Component Count and Onboard Memory

This basic unit contains one main board with a 32-bit microcontroller. The board holds 256 KB of RAM for user program execution. You will also find 512 KB of flash memory for non-volatile storage. An onboard real-time clock maintains schedule data during power cycles.

Energy Storage and Power Consumption

The ABB 1SBP260025R1001 draws 200 mA from the 5V backplane supply. A lithium coin cell provides backup power for the RAM storage. This battery maintains program and data for 180 days without external power. Therefore, the controller retains critical information during extended shutdowns.

Processing Speed and I/O Capacity

The processor executes 0.4 microseconds per basic logic instruction. It handles up to 1024 digital I/O points within a single scan. Users can store up to 1024 function blocks in the flash memory. This capacity supports automation tasks for conveyors and packaging machines.
