MPI-DN, MPI-D MULTICHANNEL ELECTRONIC RECORDER for HART or RS-485/ MODBUS RTU SENSORS            18 channels for HART / Modbus RTU sensors 2 digital channels 16 math channels 4 relay outputs for alarm or control functions 2 GB internal memory for advanced data recording color LCD TFT display USB port on the front panel with IP54 protection Ethernet port: Modbus TCP, Web Server RS 485 port: ASCII and Modbus RTU Dedicated software for visualization of measurement data Housing for panel mounting or wall mounting 20 CHANNEL FOR MEASURED PROCESS VALUES  18 channels designed to read data from sensors and instruments with digital protocol (HART or Modbus RTU).  2 digital inputs (PULS) for state, pulse or frequency measurements; OC, voltage or NAMUR configuration. HART  HART port with power supply for sensors (24 VDC /60 mA), up to 12 sensors in multidrop configuration.  Supported rev.4., rev.5., rev.6. Possible configuration as Primary or Secodary Master.  Read variables: PV - primary variable, SV – secondary variable, TV third variable, FV - fourth variable. MODBUS RTU (RS485 Port)  Sensors or instruments connected in parallel to one twisted pair of wires.  Baud rate from 1200 bps to 115200 bps.  Available functions: 03 (Read Holding Register) and 04 (Read Input Register), registers in the range 0 ... 65535.  Data format: unsigned integer, integer, unsigned long, unsigned long swapped, long, long swapped, floating point, floating point swapped. PULS INPUTS  Measurement frequency range 0.001 Hz to 10 kHz.  Pulse counting for totalisers.  Trac

MATH CHANNELS  16 math channels can display calculated result based on measured or calculated values.  Available functions: addition, subtraction, multiplication, division, square roots. ARCHIVING RESULTS  Writing to internal 2GB memory.  Text files format with the encrypted checksum, recording to one file (until end or overwrite) or to successive files (24H, week, month).  Recording time interval from 3 s to 24 h; possible to define two switched frequencies depending on alarm threshold state. 4 RELAY OUTPUTS, THRESHOLDS ALARM-CONTROL  4 solid-state relay outputs rated at 0,1 A / 60...
