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."
