Compact indicator and totalizer
CE marking and complying with RoHS

IR1700MINI UNIVERSAL TOTALIZEROUTLINEIR1700 is an indicating totalizer. Connecting with flowmeters having
pulse output, it indicates alternatively instantaneous or totalizing flowrate with alarm output. Scaling, preset value and other parameters
can be set through a key operation on front panel. Supplying built-inpower of 12 V DC for sensor, it receives 3-wire pulse signals. IR1700
compact housing of DIN48 × 24 is just the right size for your spacesaving control panel.

STANDARD SPECIFICATION● INPUT◇ Pulse input (receives pulse output signal)
Full scale input frequency setting : 1 to 1000Hz• NPN Open collector or dry contact pulse (no-voltage contact)
Voltage at open terminals: 10.0 V, Current at short circuit: 6.0 mA• Voltage pulse L: 2 V DC or less, H: 3.8 to 30 V DC
◇ External input• To receive NPN open collector output signal and contact output
signal.
Select following functions.
Reset input : Totalizing count or alarm is reset by ON input.
Inhibit input : Sensor input is inhibited by ON input(Input becomes zero compulsorily)
Hold input: Current indication is kept hold by ON input.

Totalizing count resetby key operation or reset input
Over scale
Selectable either of following• Stop totalizing with flickering indicating digit• Continue totalizing from zero endlessly• Continue totalizing with shifting(indicated as × 10)
Flow rate and totalized flow indication when abnormal signal isreceived.
The last digit flickers if input signal exceeds 150% F.S.
◇ 3 LED status lamps on the front panel
