MPI-D - Metronic AKP

Multi-channel data logger in panel case

• 20 measuring channels
• Interaction with RS-485 / Modbus RTU transducers and devices and HART devices (also in multidrop mode)
• 2 binary inputs
• 16 calculation channels
• 4 relay outputs - alarm and control functions
• Internal 2GB data memory, advanced data recording
• Color graphic LCD TFT display
• USB port on front panel with IP54 protection
• Ethernet port (Modbus TCP protocol, server www)
• RS-485 port (Modbus RTU protocol)
• Dedicated software for visualization of measurement results

Measurment channels

• 18 channels intended for reading transducers or other devices operating in the Modbus RTU standard and HART protocol transducers
• 2 channels intended for interaction with PULS-type inputs (measurement of frequencies within the range of 0.001Hz … 10kHz, pulse counting, tracking and recording the shorting / disconnecting binary signal)


• Readout of digital quantities from transducers / devices connected in parallel to a current loop
• Operation as Primary Master or Secondary Master
• Readout of variables: PV – primary variable, SV – secondary variable, TV – third variable, FV – fourth variable


• Devices / transducers connected in parallel to one pair of wires (of an RS-485(1) port)
• Transmission rate between 1200bps and 115,200bps
• Readout functions: 03 (Read Holding Register) and 04 (Read Input Register)
• Supported formats of variables: Uns. Integer, Integer, Uns. Long, Uns. Long(sw), Long, Long(sw), Float, Float(sw)

16 Calculated values

• Available functions: addition, subtraction, multiplication, division and extraction of roots

Recording measurement results

• Recording to internal 2GB memory
• Checksum secured files – protection against result errors
• Recording frequency between 3 s and 24 h; define two recording frequencies toggled upon exceeding the set alarm thresholds

4 relay outputs, alarm and control thresholds

• 4 semiconducting output relays rated at 0.1A / 60V
• Up to 4 alarm thresholds for each input and each calculated value

Other functions

• Totalizers – two totalizers per flow value (measured or calculated)
• Tracking minimummaximum and average values
• Advanced user and password system
• Event Log
• Authorized Operations Log
• Available also in wall-mounted case – MPI-DN


The MPI-D, MPI-DN recorders are used in the energy, chemical, pharmaceutical, food, metallurgical industries, manufacturing, laboratories, and wherever it is necessary to register digital measurement. Example of application: monitoring of compressed air and gas flow parameters.
