FC-33 DC Selectable Input, Isolated Signal Conditioner Input Selection Adjustments The signal conditioner can be configured for either DC milliamps or DC volts. Input and Output signal types are 0 - 5V, 0 - 10V, 0 - 20mA , 4 - 20mA . The FC-33 has built-in self-calibration, but also has OFFSET (zero) and SPAN (full scale) adjustments of the input signal. If your application requires, different span or offset (i.e. 3.6mA offset and 19.6mA span) you can adjust accordingly. 1 2 3 4 5 6 7 8 0 example: 4 - 20mA input 4 - 20mA output Application adjustments 1 Input Ranges Output Ranges 0 - 5V 1 0 1 1 0 0 1 0 0 - 20mA 1 0 0 1 1 0 0 0 Description The FC-33 has user selectable factory-calibration, but also has OFFSET (zero) and SPAN (full scale) adjustments of the input signal. The OFFSET (zero) has an adjustment range of 0 to 25% of full scale input, the SPAN (full scale) has an adjustment of 80 to 102% Application 1 2 3 4 5 6 7 8 0 - 10V *4 -20mA The FC-33 is a DIN rail mount, selectable input / output signal conditioner with 1500VDC isolation between input and output and 1500VDC isolation from 24 volt power and input / output. The field configurable input/output types allow a wide ranging capability for 0 - 5V , 0 - 10V , 0 - 20mA , 4 - 20mA .

Select the signal range (i.e. 4 - 20mA ). 2. Connect 24 volt power to the signal conditioner. 3. Connect the minimum input signal level. 4. Turn Switch 2 ON, press and hold the CAL pushbutton until the LEVEL LED comes ON steady (approx. 3 seconds), then release immediately. If the pushbutton is NOT released while the Level LED is ON steady, the signal conditioner will return to factory calibration. 5. Repeat above sequence for maximum input signal. 6. Turn Switch 2 OFF. To return to factory calibration1. Turn switch 2 ON, press and hold the CAL pushbutton until the LEVEL LED comes ON steady and then starts flashing (approx. 10 seconds), then release the pushbutton. The unit has now been returned to factory calibration. 2. Turn Switch 2 OFF. 1 0 0 0 0 0 0 0 * Must connect jumper from V+ to I+ for current input. Specifications Input Ranges 0-5V, 0-10V , 0-20mA , 4-20mA General Specifications Input impedance 250Ω ±0.1% current input 200KΩ / 400KΩ Voltage Input Accuracy vs. Temperature ± 0.005% / °C (50ppm/°C) Output Ranges 0-5V, 0-10V , 0-20mA , 4-20mA Input Power 24VDC ±10% @ 50mA Load Impedance 2KΩ minimum, voltage output 0Ω minimum, current output Recommended Fuse 0.032A Littelfuse Series 217 current inputs Maximum Load / Current 550Ω @ 24V sink/source Isolation Sample Duration Time 10mS LEVEL LED Filter Characteristic -3dB @ 3Hz , -6dB/octave 1500VDC input - output 1500VDC power - input 1500VDC power - output * applied for 1 second This LED is a powerful tool when setting up the signal conditioner. During normal operation the LED will blink at a proportional rate to the selected input signal level. When performing field calibration the LED is used for indication of the internal calibration process. Linearity Error 0.05% FSO maximum Maximum Inaccuracy of output 0.05% FSO @ 25°C (Includes offset,span,linearity) 0.25% FSO @ 0 - 60°C Stability 0.05% FSO maximum Output Current 21mA maximum (for mA output) Approx . field cal. range 0 - 25% (0 - 1.5V / 5V mode) 80% - 102% (4 - 5.1V / 5V mode) The FC-33 field configurable isolated input/output signal conditioner is useful in eliminating ground loops and interfacing sensors to our PLC analog input modules. The FC-33 has 3 way isolation, this feature solves many types of configuration problems. For example, the signal conditioner can be configured for sinking input and sourcing output. It also allows signal translation from current input to voltage output or voltage input to current output. This feature would be useful when you have limited type and number of channels in your system design, i.e. 8 channels of 4-20mA , 7 which are used and one transmitter that is 0 - 10V . CAL - Pushbutton This pushbutton along with various switch settings, allows you to calibrate the signal conditioner for your application or restore factory default calibration. Note: All data 0° - 60° C except where specified. 1 Internal Analog convertor resolution is 12 - bit. CAUTION: PRODUCT MAY BE DAMAGED IF CURRENT OUTPUT (I+/I-) AND VOLTAGE OUTPUT(V+/V-) ARE BOTH CONNECTED TO LOADS. DO NOT TIE THE I+ TERMINAL TO THE V- TERMINAL.
