Description
1. Product Description
The ABB DSDP170 (57160001-ADF) is a high-performance pulse counting board designed for industrial automation systems, specializing in precise positioning, speed, and frequency measurements. As part of ABB’s modular automation portfolio, the DSDP170 supports up to four independent high-speed pulse counting channels (2.5 MHz max frequency), enabling real-time monitoring of rotating machinery, conveyor systems, and linear actuators. Its advanced features include direction detection (forward/reverse), software-selectable resolution (1x/2x/4x/8x), and wide input voltage compatibility (5–24 VDC). The DSDP170 integrates on-board diagnostics and calibration tools, ensuring reliability in harsh industrial environments while simplifying maintenance. Ideal for applications requiring accurate motion control, the board is widely used in manufacturing, energy, and transportation sectors.
