ABB 1SBP2605002R1001 Remote Unit

This remote unit expands I/O capacity for ABB Advant Controller 31 systems. It connects to the main CPU via a fieldbus network for distributed control. Therefore, this component suits applications requiring I/O points located away from the main rack.

Physical Dimensions and Weight Specifications

The ABB 1SBP2605002R1001 features a rugged 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 unit alongside other Advant modules.

Interface Types and Connection Layout

The ABB 1SBP2605002R1001 provides one RS-485 port for fieldbus communication. A second 20-pin backplane connector links to local I/O modules. The front panel carries LED indicators for network and module status. Hence, operators can verify remote communication health at a glance.

Component Count and Remote I/O Architecture

This remote unit contains one main board with a 16-bit communication processor. The board holds 128 KB of buffer memory for data exchange. You will also find a power supply section for local I/O modules. An onboard real-time clock synchronizes data with the main CPU.

Energy Storage and Power Consumption

The ABB 1SBP2605002R1001 draws 250 mA from the 5V backplane supply. It also requires an external 24V supply for local I/O module power. A supercapacitor maintains configuration data for 48 hours without main power. This storage retains settings during brief network interruptions.

Communication Performance and Diagnostics

The unit exchanges data with the CPU every 5 ms cycle time. It supports hot-swap replacement of local I/O modules during operation. Users can read detailed diagnostics via the Advant controller software. This feature reduces downtime for remote I/O maintenance.
