MODEL: 18KPR

Rack-mounted DCS Signal Conditioners 18K-RACK

[3] OPTIONS

Power Switch

blank: None

PULSE SCALER

Functions & Features

/S: With power switch

• Takes pulse measurements from turbine meters or

volumetric flowmeters and outputs in convenient

engineering unit

CAUTION

1) This unit's output waveform is not uniform due to its

• Module can be retracted without removing wiring for an

insulation test

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.

• Optional power switch

3) Use M-System’s Model M2PRU instead of this unit in

conjunction with the pulse output from M-System’s power

transducers.
