MODBUS AND 4-20 mA TRANSMITTERS FOR PULSE, RPM, COUNTER, ETC. DMM-4000/..
The DMM-4000/.. Series are two loops configurable field transmitters for specific variables with inputs adapted to each variable (DMM-4000/... where the suffix shows the version), e.g. Chemical (pH, Conductivity, etc.), Electric (V, A, RMS, etc.), Humidity (HR, HA, Enthalpy, Dew point), Pressure, Level, Flow, Pulse Counter, Vibration, Weight, etc.

Allows with low cost to use the old probes and classic sensors placed on field and to transmit them toward control systems as PC or PLC in mA and Modbus saving A/D and D/A conversion tasks. In option, they can be to communicate by Radio 868 MHz (915 MHz in USA) or by Ethernet, cable or WiFi, by means adapter modules RMT, EMT or WMT-1000 Series.
Pulse Counter, Frequency and Period, RPM, PWM Signals

Several versions are available to measuring and to transmit these signals:
• Specific Version for Pulse Counter
• Specific Version for Frequency and Period
• Specific Version for RPM
• Specific Version for PWM Signals
