KYOWA CFV-90A F/V Converter Card Multi Signal Conditioner

Measuring Targets

AC signal
Pulse signal (including open collector signal)

Frequency Range

0.2 Hz to 100 kHz
*When set to 1.0 V output and 20 kHz range, 100 kHz input can measure as
5 V.

Input Voltage

±0.5 to ±50 V

Input Coupling

AC or DC
Select by switch operation.

Trigger Level (Input Detection Level)

0.0 to 5.0 V
Trigger level is set from the 2-digit thumbwheel switch in 0.1-V step.
*When trigger level set to 5.1 V or more, trigger level saturates at 5.0 V.

Nonlinearity

Within ±0.1% FS

Sensitivity Adjustment (RANGE)

500, 1k, 2k, 5k, 10k, 20k Hz (6 steps)

Full scale of the range is output with the voltage set with the OUTPUT switch (3-digit thumbwheel switch).

Accuracy: Within ±(0.1% + 5 mV)

[Setting Example]
When SET is executed with RANGE set to 20 kHz and OUTPUT switch set to 1.0 V, 1.0 V output at 20 kHz input, 5.0 V output at 100 kHz input.

Calibration (CAL)

100% or 50% of each RANGE
Accuracy: Within ±0.5%

Response Time

When frequency continuous:
Less than one cycle of the input signal + 25 μs or less
(At the start of output voltage rising)

When frequency cutoff :
Less than two cycle of the input signal + 25 μs or less
(At the start of output voltage falling)

Power Supply to Sensors

12 VDC ±10% (At load current is 50 mA or less.)

Noise

30 mV_P-P or less
(When input the signal: Square, frequency 100 kHz, amplitude: ±0.5 V)

Stability

Temperature
Zero point: Within ±0.01% FS per ºC
Sensitivity: Within ±0.01%/ºC

Time
Zero point: Within ±0.05% FS per 8 h
Sensitivity: Within ±0.05%/8 h

Output

Dual output, both BNC connector and integrated connector output the same signal.

Voltage output: +5 V or more, when load resistance 5 kΩ or more
Zero adjustment: -0.1 to 0.1 V or wider

Output Off Function

Available

Output Impedance

2 Ω or less

Withstand Voltage

500 VAC for 1 min, between the following two positions respectively:
　Input and output
　Input and case
　Output and case

Over Input Indication

LED lights up.

Connector Type

Input connector: NDIS4109 (Small round 9 pins)
Output connector: BNC

Dimensions

24 W ×96 H ×170 D mm (Excluding protrusions)

Weight

Approx. 140 g
