Product Description:

The FV31S00 CONVERTER UNMP from Danaher is a frequency-to-analog signal converter made for tracking and control systems that need to change signals precisely. Because it takes a frequency input and gives out a proportional analog output, the device can be used in industrial automation processes.

The FV31S00 CONVERTER UNMP works with 50/60 Hz line frequency and 120 VAC input power at 6 VA. For safety, it comes with a 1/8 Amp SLO-BLO fuse. It has terminals for setting the alarm, setting the 4 mA and 20 mA outputs, adjusting the gain and offset, connecting the frequency input, the analog output, the common wire, the voltage outputs, shielding or ground, and connecting the AC power through L1 and L2. You can change the analog output by setting 4 mA and 20 mA reference points on the OUT wires. The product has separate GAIN and OFFSET terminals that let you tune the output and help you measure the signal accuracy. The input frequency is converted from a pulse rate to an analog range that can be adjusted via the INPUT port. The COM interface makes sure that all analog signals have the same starting point. The +V OUT and -V OUT terminals let you send voltage, which works with voltage-based analog systems. Grounding is done correctly with SHIELD and GND. The general setup makes it possible for PLCs and analog modules used in control systems to work together.

Following the rules in IEC 60068-2, the FV31S00 CONVERTER UNMP can handle movements of 10 to 20 g and shocks of up to 100 g. The temperature range for this converter is typically between -20°C and +85°C. The converter is engineered to maintain the reliability of signals, even in environments with non-condensing relative humidity levels of up to 95%. The converter UNMP has features that are necessary for industrial automation systems that need to change frequency to current or frequency to voltage. The converter meets the needs of system integration when data scaling and precise adjustment are needed.

Frequently Asked Questions about FV31S00:

Q: Does FV31S00 CONVERTER UNMP support voltage output terminals?

A: Yes, it includes +V OUT and -V OUT. These allow connection to voltage-based analog systems requiring 0–10 V output scaling.

Q: Why does FV31S00 CONVERTER UNMP have offset adjustment?

A: OFFSET terminal lets users fine-tune the zero-scale output. This ensures accurate signal calibration relative to the input frequency.

Q: How does FV31S00 CONVERTER UNMP handle power input?

A: It operates on 120 VAC at 6 VA. Power is supplied via L1 and L2 terminals for stable internal conversion.

Q: Do FV31S00 CONVERTER UNMP terminals support alarm setting?

A: Yes, the ALARM SET terminal allows integration with alarm logic. It supports triggering conditions based on signal thresholds.

Q: Why does FV31S00 CONVERTER UNMP include a SHIELD terminal?

A: SHIELD provides proper grounding for noise reduction. It enhances signal integrity when frequency input lines are exposed to electrical interference.
