Technical Description of DSDP 170 (Part Number: 57160001-ADF)
1. Product Overview and Core Identity
The DSDP 170 (part number: 57160001-ADF) is a high-performance Pulse Counting Board developed by ABB, belonging to the S100 I/O module family. It is specifically engineered for precision industrial measurement applications, integrating dual core functions: position/length measurement (via pulse counting) and speed/frequency measurement (via pulse frequency analysis). Designed to handle high-speed pulse signals with a maximum frequency of 2.5 MHz, this board is ideal for demanding automation scenarios such as high-speed motor speed control, precision conveyor positioning, and industrial process length metering—where real-time, accurate data acquisition is critical.
Notably, the DSDP 170 is exempt from the RoHS Directive (2011/65/EU) under Article 2(4)(c), (e), (f), and (j), as validated in ABB’s EU Declaration of Conformity (document: 3BSE088609). This exemption applies to equipment used in critical industrial process control systems, aligning with its role in supporting high-reliability automation infrastructure. Classified as an I-O_Module, it serves as a vital interface between pulse-generating field devices (e.g., high-speed encoders) and upper-level controllers (e.g., ABB Advant Controller 450, 800xA DCS).
