Instruments
The converter current output electrical isolation has been achieved. Output to take an active
approach. Current output mode 4-20mA, 20mA current output value from the corresponding traffic
parameter item "scale flow of value" is determined (reference to factory nameplate on the
instrument measuring range a value). The maximum current output load resistance of 750Q, the
load resistance includes the cables used to connect the resistance. Current output cable is
recommended RWP2x16/015 PVC insulated sheathed cable shield. 2.
Counter
The Transmitter frequency, pulse output has been achieved electrical isolation, the output for the
active mode (see above chart). Transmitter frequency, pulse output with transistor output mode.
Maximum pulse output frequency 5KHZ, the output pulse amplitude of 24V. Active mode the
maximum load current 50mA, passive mode the maximum load current 0.2A. As the frequency
and pulse output terminals are shared, it is not to choice two output modes. Users can set the
parameter "frequency output" to select the work. Frequency output upper limit corresponding to
the measured flow value by the parameter item "scale flow value" decision (reference instruments
to measure the scope of a factory nameplate values). Pulse output equivalent by the parameter
'pulse equivalent L / P "decision.
Transmitter communication with RS485, MODBUSASC, MODBUSRTU communications
capabilities (requires a user specified when ordering). Available through the "485 output
communication protocol" parameter is set to specify. Instrument Communication Interface specific
technical note on "protocol."
