Voltage data-logger / pressure / humidity / temperature

Data logger with 2GB internal flash memory. The recorder is intended to measure process values in industrial applications. It is designed to work with devices and sensors that communicates by digital bus: RS-485 standard with Modbus RTU protocol and HART standard (also in multidrop configuration).

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 imputs (PULS) for state, pulse or frequency measurements; OC, voltage or NAMUR configuration.
HART:
HART port with power supply for sensors (24 VDC /50 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,
tracking a binary signal (short or open circuit).
16 math channels can display calculated result based on measured or calculated values.
Two totalisers for each channels (measured or calculated); possible also to read values directly from the transmitter via HART or Modbus RTU.
4 relay outputs for alarm or control functions.
