6PA

Field-mounted Two-wire Signal Conditioners 6-UNIT

FREQUENCY TRANSMITTER
(field-selectable freq. range)

Functions & Features
• Converting the output from a pulse-type transducer into a standard 4 – 20 mA DC signal
• Field selectable frequency range
• Rugged enclosure
Typical Applications
• Positive displacement flowmeters, turbine flowmeters and vortex flowmeters
• Proximity switches
• Oval flowmeters

MODEL: 6PA-2

ORDERING INFORMATION
• Code number: 6PA-2
• Frequency range (e.g. 0 – 500 Hz)
User’s frequency range specified when ordering determines the field adjustable range of the 6PA. Refer to the table below and check the range before ordering.
ORDER SPECIFIED FREQ: ADJUSTABLE RANGE
36 Hz – 100 Hz: 36 Hz – 120 Hz
100 Hz – 240 Hz: 90 Hz – 300 Hz
240 Hz – 480 Hz: 180 Hz – 600 Hz
480 Hz – 1.0 kHz: 360 Hz – 1.2 kHz
1.0 kHz – 2.4 kHz: 0.9 kHz – 3.0 kHz
2.4 kHz – 4.8 kHz: 1.8 kHz – 6.0 kHz
4.8 kHz – 12 kHz: 3.6 kHz – 12 kHz
• Mounting adapter (e.g. surface mounting adapter plate, model: A-01)
