Description
The P1WX-IBS true power monitor is
enclosed in a 45 mm wide P-93
housing. There are 3 versions with
different voltage ranges available.
Each version can
- monitor either a three-phase load,
- two AC loads
or
- two DC loads.
Features:
● Status LEDs are in accordance
with guidelines of the Interbus
Club
● Currents can be measured in
4 different measuring current
ranges, 25 mA ... 10 A
● Switch thresholds for under and
overload can be set separately
● Max. 4 adjustable switching
thresholds
● Hysteresis can be set for each
switching threshold
● “Teach-in” mode to establish ideal
process settings or threshold
values
● Reset latch
● Start-up delay time ta can be set
● Non-volatile mekory of set values
(50 different parameter sets)
AC/DC: 10 ... 70, 60 ... 450, 100 ... 750 V
AC: 0.5; 1; 5; 10 A
DC: 5, 10 A
U, I: < ±5 %

connector
● Detects values which exceed
measurement range (current and
voltage)
● Measurement principle: Aron
circuit (rated true power without
neutral conductor monitor)
● For currents > 10 A: Current
transformer input
The P1WX-IBS monitors the rated
true power of electrical loads. It is
intended for use in industrial environments and is characterised by its
bus capabilities. The P1WX-IBS is
designed as an Interbus slave
connection for the remote bus.
