Druck DPI620G-IS-FF Genii IS Multifunction Calibrator Unit

Module Feature

DPI620G-IS-FF is the intrinsically safe version of Druck Genii series multifunction calibrator, FF stands for FOUNDATION Fieldbus communication option. It is a modular portable calibration host, compatible with PM620 interchangeable pressure modules and PV624 pressure control station. It can source and measure mA, mV, voltage, resistance, frequency, RTD and thermocouple signals, built-in loop power supply. It supports FOUNDATION Fieldbus device configuration, parameter read/write and diagnostic, also compatible with HART. 4.3-inch color touch screen, internal data logger, auto calibration wizard, hot-swap battery for hazardous zone operation. ATEX / IECEx certified for Zone 1, widely stocked as maintenance spare for SIS and FCS instrument loop calibration in hazardous process plant.

Working principle

The internal precision reference circuit outputs or captures analog process signals. When matched with pressure module, it reads pressure value for gauge, transmitter and pressure switch calibration. Fieldbus communication circuit establishes digital link with FF field instruments, downloads tag, range, PID and diagnosis parameters. The logger stores calibration records, and the built-in safety circuit meets intrinsic safe energy limitation for explosive atmosphere.

Onboard components

Main control CPU, precision signal reference board, FF/HART communication module, touch LCD display, signal terminal group, rechargeable intrinsic safe battery pack, internal flash memory, USB service port and rugged sealed enclosure.

LED indicators

LCD touch screen displays measured value, calibration result, fieldbus device information and alarm codes. LED indicators: Power, Communication, Battery status.

Hardware self‑diagnosis

Built-in supervision detects signal overload, battery low, communication error and internal reference drift. Calibration management and FF device configuration are completed by Druck Calibration Manager software.

Programming softwareCalibration Manager, used for calibration task creation, record storage, FF instrument parameter configuration, firmware upgrade and report export.
