Electrical connection (4-20 mA current output)
The 2-wire 4-20 mA current loop combines the transmitter
output signal and supply voltage in one cable where the
current consumption represents the measurement signal.
The 4-20 mA signal complies with the NAMUR NE 43
standard.
A current loop resistor () value of 250 ohms is commonly
used and will provide a 1-5 VDC across the resistor. The
current loop resistor value can be chosen freely up to a
maximum of 800 Ohm, provided that the minimum and
maximum supply voltage range is respected.
INFORMATION: The loop current resistor should
have a low temperature drift coefficient to ensure
best measurement performance.

Signal to pressure conversion (4-20 mA current output)
The transmitter with 4-20 mA current output is available with
different pre-configured output scaling.
The current signal () can be converted to pressure using the
following linear expression:

Where and
are the minimum and maximum
pressure, respectively; and are the minimum and
maximum current, respectively.
ATTENTION! The PCM-1 has a built-in self-diagnostic
and in case of product failure the current output will
provide a fault signal in the range of 3.2 - 3.6 mA in
compliance with the NAMUR NE43 standard. Replace
the unit in case of receiving a fault signal.
User configuration of current output scaling
The S4-Connect™ interface enables flexible user configuration
of the analog current output. The minimum and maximum
output current and pressure can be set to any value within the
valid range for the transmitter. For more information refer to
