(1 N/O and 1 N/C)
● Digitally adjustable response value
from 0 ... 99 % of the nominal
value
● Adjustable response delay
● Adjustable start-up suppression
time
● Automatic or manual reset
● LED for status display
● Versions available for digital or
analogue remote control operation
230, 240 V
DC1: 24 V/5 A/250 W
- 12 V DC (current flow 3 mA)

connector
The P1K is used to compare true
and set values. The output relay
switches if the measuring voltage
exceeds the response value. The
release value is adjustable from 1 to
30 %. If the measuring voltage falls
below the release value, the output
relay returns to its original position.
The offset function causes the unit to
operate using differential evaluation.
This offsets the response value.
If the permitted voltage range is
reached once more the device will
start automatically if set to automatic
reset. If manual reset is used, the
supply voltage must be interrupted
using an external reset button.
