FLOODING RELAY 3-LEVEL TYP: PZM-20
Product Description
The PZM-20 device is used to detect the
presence of conductive liquids. Detection
levels of liquid and of mounted sensors
are the same. The device can be used to
activate different circuits (mostly pumps)
depending on the liquid level. PZM-20
cooperates with SZH-03 sensors produced
by ZAMEL Sp. z o.o. The sensitivity
of a sensor detection can be adjusted
in the range of 1 ÷ 190 kΩ by means
of a potentiometer placed on the front
panel. The device output is equipped
with three relays of a maximum contact
load 16 A. The use of changeover
contacts NO/NC increases the device
(PZM-20) application range. The red
LEDs (PK1, PK2, PK3) indicate that
a particular output is switched on. The
green LED indicates the presence of 230
V AC supply voltage. The PZM-20 relay is
designed to be mounted on a rail (TH35)
in distribution boards. It is made in a
3modular casing.
