standard process signal

• Built-in excitation

• Field-selectable input type and range: Open collector,

mechanical contact, voltage pulse or two-wire current pulse

• High-density mounting

Typical Applications

• Positive displacement flowmeters, turbine flowmeters and

vortex flowmeters

• Measuring rotation speed of a machine generating dry

contact signals

MODEL: WJPAD2-[1][2][3]-[4][5]

ORDERING INFORMATION

• Code number: WJPAD2-[1][2][3]-[4][5]

Specify a code from below for each of [1] through [5].

(e.g. WJPAD2-7A6-K/Q)

• Special output ranges (For codes Z & 0)

• Use Ordering Information Sheet (No. ESU-2275). Factory

setting (indicated below) will be used if not otherwise

specified.

• Specify the specification for option code /Q

(e.g. /C01/S01)

Note: When the user requires a current and a voltage

output, specify the current to be the Output 1 which allows

a greater load.
