OEM TRANSDUCER–CFC-OG - Input Isolated Current to Frequency Converter Industrial Super Transducer. With Offset and Gain adjustments.

 

The TRANSDUCER–CFC-OG Isolated current to frequency converter is a current 4-20mA signal to frequency pulse 1KHz to 5KHz or 2KHz to 10KHz (Proportional) super transducer board for HVAC (Heating, Ventilation and Air Conditioning), electro-hydraulic and servo electronics; actuator, dampers, bleed pilot valve, globe valves, butterfly valves, plug valves, dampers and more. Commonly utilized as the heart of CFC In-Line Amplifier CFC-ILA.

 

The TRANSDUCER–CFC-OG board is designed to perform current to frequency conversion (transducer). If used properly, it will eliminate the need for an expensive board, which would otherwise be needed to carry out the same tasks.

 

The TRANSDUCER–CFC-OG  is easy to install, setup, and operate. If you want to do professional current to isolated frequency related functions, The TRANSDUCER–CFC-OG offers the features you need. It can be mounted easily via 0.125" mounting holes using 4-40 screws.

 

Simply connect the board to power connect your current source i.e. 4 to 20mA to the board input and it will convert it to frequency pulse 1-5KHz or 2-10KHz (model depended).

 

Note: 1HZ = 60RPM therefore 10KHz => 600000 RPM. We chose input of 4 to 20mA because standard PLC and industrial interface excepts transducers with 0-10KHZ input. Whoever we also have 1-5KHZ and 2-10KHZ models.

 

 

Our TRANSDUCER–CFC-OG OEM Isolated Current to Frequency Converter (CFC) board is designed to convert a an analog current to optical isolated continuous series of digital pulses (frequency).

 

Super performance in is class; The Industrial board Offset and Gain adjustment allows the unit to deliver full-scale output frequency for any current input  within the limits of current and frequency range rating. It will provide an ultimate combination of fast response and low ripple.

 

Note: For systems that requires opto isolated signal output i.e. current to voltage converter, use our OEM FVC (frequency to Voltage board) together with the ISO CFC board. I.e. The industrial signal 4-20mA will convert to isolated frequency 2-10KHZ and then back to 2-10VDC.

Board Powering--

 

Below are some power supply example for generating -/+ 15VDC required to power the isolated current to frequency transducer. The module requires a bipolar 30VDC power supply (+/-15 V DC) for operation.

 

 

One can use our POWER-AC3PNDC-15LD a Low Current Dual Output 15 & -15 Voltage DC power supply board/Regulator Interface board with step-down power transformer (110V/60HZ primary) shown above on the (left) to power the isolated current to frequency converter board (right), mounted in EID1593KBK sold separately.
