Overview

The ABB DSDP140A is a multifunctional pulse counter board designed for ABB’s Advant Master Process Control Systems. It combines pulse input, digital I/O, and analog output capabilities, making it ideal for high-speed control applications such as positioning loops, rotary encoders, and event counting.

The module features a three-channel pulse input loop capable of handling ±15 mA at up to 80 kHz, ensuring precise signal acquisition from pulse generators. Additionally, it includes 2 digital inputs, 4 digital outputs, and 1 analog output with 11-bit resolution plus sign, supporting 0 to +10 V or ±20 mA ranges. Its compact, robust design is suitable for demanding industrial environments.

For example, in a packaging line, the DSDP140A can count encoder pulses to track conveyor movement and trigger actuators based on position thresholds.

Technical Data

Typical Applications

• Rotary Encoder Feedback: Counts high-speed pulses for position tracking and motion control.
