Conductive Level Controller 61F-GPN-BT/-BC CSM_61F-GPN-BT_BC_DS_E_5_2 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 kΩ, allows use for a wide variety of liquids. • Relay contact chattering conventionally caused by waves elim- inated using open collector output, reducing contact wear. • Meets CE marking and is a UL recognized component. Refer to Safety Precautions for Floatless Level Controllers. Features The 61F can now run on DC power to allow energy savings, greater safety, and use in emergency situations. Open Collector Output Combines DC Power Oscillator Supply with AC Sensing Signals can be used as circuit Chattering Method direct input for a PLC. Detector Load circuit AC sine-wave signals are PNP output is also sent to electrodes using a possible using the built-in DC-AC converter, connection method. preventing electric corrosion and ensuring safety.

(Operation shown in parentheses in the diagram above.) 2 ON OFF 61F-GPN-BT/-BC ■ Reading Signals for the Liquid Level Only (No Control) Only E1 and E3 are used. Output will turn ON when the liquid level reaches E1 if terminals 7 and 8 are open, and will turn OFF if terminals 7 and 8 are closed. Also, to take signals for liquid level at several points, use terminal 4 as a common for all of the Controllers and use terminal 5 of each Controller as an electrode. Note: If terminals 7 and 8 are shorted, operation of the 61F relay is “de-energizing” (i.e., energized normally and de-energized when liquid is present across the electrodes). Therefore, if the power supply connected across terminals 3 and 9 is interrupted, the output from terminals 10 and 11 will turn OFF, enabling detection of power interruptions.
