3BSE013228R1 DP820 Pulse Counting Module: Technical Overview
The 3BSE013228R1 DP820 is a high-performance two-channel pulse counting module designed for
ABB Compact Product Suite, specialized in processing signals from incremental pulse transmitters. It
enables simultaneous position/length measurement and speed/frequency detection, making it ideal
for industrial applications like motion control, material handling, and process monitoring.
Core Features & Benefits
Two independent channels, supporting pulse transmitters with RS422, +5 V, +12 V, +24 V, and 13 mA
interfaces.
Dual measurement capabilities: Bidirectional 29-bit counters for position/length accumulation, and
frequency/speed measurement ranging from 0.25 Hz to 1.5 MHz.
Per-channel hardware: Three balanced inputs for pulse transmitters, one digital input, and one digital
output, plus configurable sensor power current limiting via compatible MTUs.
Full galvanic isolation: Channels are isolated from each other and the circuit common to prevent
electrical interference and ensure measurement accuracy.
Wide compatibility with ABB Module Termination Units (TU810V1, TU812V1, TU814V1, TU830V1,
TU833) for flexible installation.
