Mpro configuration software
The digital display M2229 is used to indicate or monitor any sensor signal. It converts the input sensor signal to a programmable display for example 0 to 100.0%. In this range two alarm contacts can be set independently. A 4-digit LED display shows the actual value and setpoints or alarm values in the range of -1999 to 9999 units. All settings can be set directly at the M2229 or with a personal computer or a laptop. The values of the user menu can be protected from unintended access using an access code.
A typical application would be to measure and monitor pressure in a process vessel. The pressure transmitter converts the pressure of 1 to 10 bar to a current signal of 4 to 20mA. The M2229 monitors under- and overpressure in the vessel. It converts the 4... 20mA signal current to 0...100.0%. The alarm is set between 0% (=1 bar) and 100.0% (=10 bar). With these floating alarm contacts, overpressure valves, compressors, etc. are driven directly.
Optionally, a galvanic isolated output signal of 0...20mA or 4...20mA is available.
