User manual OMRON 61F-GPN-BC DATASHEET

[. . . ] · Relay contact chattering conventionally caused by waves eliminated 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. Oscillator circuit Detector circuit Open Collector Output Signals can be used as direct input for a PLC. PNP output is also possible using the connection method. Chattering Load Supports Multi-channel Sensing Power supply circuits and detection circuits are isolated, allowing more than one Controller to be used in the same tank. Upper limit Mid-point Lower limit Control output is possible for upper limit, mid-point, and lower limit. 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). [. . . ] (at 500 VDC) 2, 000 VAC, 50/60 Hz for 1 minute 2 W max. Releasing: 3. 0 s max. Note: The dielectric strength is measured between power terminals and electrode terminals, power terminals and output terminals, and between electrode terminals and output terminals.

OMRON S8VS Note: The part within the dotted-line box is for the 61F-GPN-BC (relay-output type) only. Automatic Water Supply Operation Short terminals 7 and 8 for automatic water supply operation. (Operation shown in parentheses in the diagram above. ) E-16 Conductive Level Controller 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.

Meet safety standards by using DC power supply for all devices in a panel. Liquid level control for waste-heat recovery boilers in co-generation systems. Applications ON OFF Liquid level control for solar power generation systems. Liquid level control for remote regions without AC power supply. Cut costs by using the 61F in situations where ultrasonic/electrostatic capacity level controllers were used because only DC power supply was available. Number of controllers required: Battery 2 1 Conductive Level Controller 61F-GPN-BT/-BC E-17 Level Controllers Precautions General Precautions Before using the Controller under conditions not described in the relevant documents or applying the Controller to nuclear control systems, railroad systems, aviation systems, vehicles, combustion systems, medical equipment, amusement machines, safety equipment and other systems, machines, and equipment that may have a serious influence on lives and property if used improperly, consult your OMRON representative. Make sure that the ratings and performance characteristics of the Controller are sufficient for the systems, machines, and equipment and be sure to provide the systems, machines, and equipment with double safety-mechanisms. Correct Use Mounting Mount to a panel of thickness 1 to 5 mm. Do not mount the Controller in the following places. · Locations subject to strong vibrations or shocks. · Locations outside the specified temperature and humidity ranges, or locations prone to condensation. (The Controller detects high impedances. [. . . ] · Do not short the load connected to the output terminals. · Do not connect the power supply in reverse. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
