ABB DSDP140A 57160001-ACT Pulse Counter Board
Description: 
DSDP140A Is part of Advant Controller 400 series process controllers. The S100 I/O consists of several I/O boards, internal cables, and connection units covering awide variety of applications and specific needs.The I/O boards are divided into groups, depending on their function. Within each group, there are several I/O boards with differing functionality and complexity. 
The range of process I/O modules is complete, consisting of general purpose digital and analog inputs and outputs and special interfaces for special tasks. These specials include pulse counting, frequency measuring, positioning, motor speed control and communication with other controllers. All I/O modules provide simple interfacing, accurate - yet fast control, and easy integration of individual loops into a comprehensive plant-wide control and supervision system.
For one positioning loop, consisting of: 
Pulse inputs: 3 (A, B and STROBE), ±15 mA, max. 80 kHz
DI/DO: 24 V d.c. DO max. 150 mA AO: ±10V/±20 mA, 11 bits resolution
One positioning loop input for pulse generator: three channels, ±15 mA, max. 80 kHz
Galvanic isolation: Opto-coupler
Connection unit: DSTD 150A orDSTD 190
There are four different types of pulse counter boards: DSDP110, DSDP140A, DSDP150 and DSDP170.
