ABB DP620 3BHE300016R1 Pulse Counter

Precision High-Speed Counting

The ABB DP620 3BHE300016R1 delivers elite precision for industrial timing and counting tasks.¹ As a high-speed counter module within the S800 I/O family, it processes pulse signals with an exceptional accuracy of $\pm 0.01\%$. Whether you are monitoring turbine speeds or high-frequency encoder feedback, the DP620 captures data across a broad measurement range up to 10 MHz. Its 1-microsecond resolution ensures your control system receives the granular data necessary for ultra-precise motion and flow control.

Seamless System Integration

Engineered for the S800 I/O range, the DP620 3BHE300016R1 integrates effortlessly into ABB’s DCS architectures. The module operates on a standard 24V DC power supply, supporting both 5V and 24V pulse inputs to accommodate various sensor types.² Its compact footprint (4.3cm width) maximizes rail space, while the “Hot Configuration in Run” (HCIR) capability allows you to maintain process uptime during system modifications or maintenance.

Robust Performance in Harsh Environments

The DP620 3BHE300016R1 features a rugged design tailored for the most demanding industrial sectors.³ It maintains reliable performance across a wide operating temperature range of -20°C to +70°C and survives extreme storage conditions from -40°C to +85°C. This durability, combined with its lightweight 0.16kg construction, makes the DP620 a dependable choice for offshore platforms, chemical plants, and power generation facilities where environmental resilience is critical.
