ABB 1SBP260601R1001 Extension Module for AC500 I/O Expansion

The ABB 1SBP260601R1001 expands the input and output capacity of AC500 PLCs. You can connect this module remotely via the system bus cable. It adds eight digital inputs and eight digital outputs to your configuration. This extension suits distributed control applications with physical spacing constraints.

Technical Specifications and Hardware Layout

This extension module measures 112 mm in height. Its width reaches 67 mm, and the depth equals 76 mm. The ABB 1SBP260601R1001 weighs approximately 0.22 kilograms. A single internal PCB contains all input filtering and output driving circuits. The module provides eight 24 V DC input channels for field sensors. Additionally, it delivers eight transistor output channels for actuator control. The unit stores no energy in capacitors or batteries. One 40-pin front connector handles all field wiring connections.

Input and Output Electrical Ratings

The ABB 1SBP260601R1001 accepts input signals from 0 V to 30 V DC. Each input draws a typical current of 4 mA at 24 V DC. The module filters input transitions with a programmable debounce time. For outputs, each transistor channel switches 0.5 A at 24 V DC. The total output current per common returns to 4 A maximum. Consequently, this module drives small contactors and indicator lights reliably. Short-circuit protection on outputs prevents damage during installation errors.

Bus Connection and Installation Guidelines

You must connect this module using the dedicated extension bus cables. Transitioning to addressing, the module automatically obtains its position from the CPU. Two front LEDs indicate power status and bus communication activity. You can mount this unit up to 100 meters away from the main PLC. The operating temperature range extends from -20°C to +60°C reliably.
