High-density Signal Conditioners 10-RACK
[3] OPTIONS
blank: none
PULSE SCALER
Functions & Features
/Q: With options (specify the specification)
• Converting pulse rate into convenient engineering unit for
display on a totalizing counter or meter
SPECIFICATIONS OF OPTION: Q
COATING (For the detail, refer to M-System's web site.)
/C01: Silicone coating
Typical Applications
• Positive displacement flowmeters and turbine flowmeters
• Magnetic tachometers
/C02: Polyurethane coating
/C03: Rubber coating
CAUTION
1) This unit's output waveform is not uniform due to its
scaling method.
2) Use input relays which do not cause chattering (e.g.
mercury relays). Other relays could be used only with a CR
filter, for 10 Hz at maximum.
3) Use M-System’s Model M2PRU instead of this unit in
conjunction with the pulse output from M-System’s power
transducers.
