ABB DSDP 170 57160001-ADF Pulse Counting Board

DSDP 170 57160001-ADF Pulse Counting Board

DSDP 170 is an advanced quad-channel pulse counting board for incremental pulse transmitters. Each channel contains counters and registers for position or length and speed or frequency measuring and a programmable clock generator for setting the measuring interval. The counters can count up or down at a maximum pulse frequency of 2.5 MHz. The direction of counting is determined by a quadrature decoder or by defined pulse inputs for up-and-down counting.

Each measuring channel is equipped with:

• Pulse inputs

Balanced inputs for 5, 12, 24 V, 13 mA or RS 485 Line-drivers. All channels are individually isolated. The inputs are matched to the desired signal level with solder jumpers on the connection unit. The input impedance for 5 V/13 mA is 200 Ω, for 12V 680Ω and 24 V 1.1 kΩ. The pulse inputs consist of:

– Two individual, opto-isolated pulse inputs for 90° phase-shifted signals for direction sensing or separate pulse signals for up-and-down counting. These inputs are later referred to as channel A (CHA) and channel B (CHB).

– One individual, opto-isolated pulse input for strobe (revolution) pulses from incremental pulse transmitters. Used for synchronization of the position counter. 

This input is later referred to as channel C (CHC).

• Digital input

An individual, opto-isolated pulse input for synchronizing of the position counter. The voltage level is +24 V. This input is later referred to as DI.

• Digital output

An Opto-isolator , short-circuit-proof digital pulse output from the coincidence comparator. This output can be used to control external objects. Programmable pulse length, 24 V d.c., 250 mA. This output is later referred to as DO.

The process signals are connected to the connection unit DSTX 170, which is connected to the DSDP 170 board with the screened pair twisted cable DSTK 199. The transducers are connected via screened cable to the connection unit DSTK 170. Power supply for the transducer and auxiliary power supply for the digital input and the digital output are also applied to the connection unit.
