Conductive Level Controller
61F-GPN-BT/-BC
Battery (24 VDC) allows use in locations
without AC power supply. AC sine-wave
voltage between electrodes enables stable
detection with no electric corrosion.
• Outputs can be set to self-hold at ON or OFF using special cir-
cuits.
• Adjustable sensitivity, with an operating resistance range of 0 to
100 k , allows use for a wide variety of liquids.
• Relay contact chattering conventionally caused by waves elimi-
nated using open collector output, reducing contact wear.
• Bears CE marking and is a UL recognized component.
Features
The 61F can now run on DC power to allow energy savings, greater safety, and use in
emergency situations.
Combines DC Power
Supply with AC Sensing
Method
AC sine-wave signals are
sent to electrodes using a
built-in DC-AC converter,
preventing electric
corrosion and ensuring
safety.
Supports Multi-channel
Sensing
Power supply circuits and
detection circuits are
isolated, allowing more
than one Controller to be
Mid-point

used in the same tank.

Conductive Level Controller
Open Collector Output
Signals can be used as
direct input for a PLC.
PNP output is also
possible using the
connection method.
Same Wiring for Supply
and Drainage
Supply control and
drainage control can be
performed with the same
wiring (short terminals 7
and 8 for supply control).
This makes it easy to
perform wiring and
confirm connection.
