Dynapar FV3 Frequency to Voltage Converter

Description

Overview / Design Principle: Dynapar FV3 frequency-to-voltage converter measures a pulse input frequency and converts it to an analog 0 to +10 VDC or 4-20 mA output proportional to machine or process speed. When used with a Dynapar encoder, it converts the frequency content of the encoder to an analog signal for operating chart recorders, or for supplying velocity feedback in closed loop speed control systems.

A wide range of digital pulse transducers, application speed ranges, and converter response times can be configured via jumpers. The FV3 also includes 12 VDC transducer supply power.

Quick Specs…

• Delivers 0 to +10 VDC or 4-20 mA outputs proportional to input pulse rate (frequency).
• Accepts variable pulse rate inputs from a variety of sensors.
• Linearity ± 0.2% maximum.
• An FV3 and an encoder replace a DC Tachometer when precision feedback is required.

Features and Benefits:

Electrical Features

• 0 to +10 VDC or 4-20 mA analog output.
• Linearity is typically ±0.1% of full scale.
• Switch selectable 115 or 230 VAC, 50/60 Hz power.
• Jumper selectable input frequency range.
• Built-in transducer power supply.
• Front-mounted terminal strips for field connections.
• Potentiometer adjustments (gain, offset, 20 mA set and 4 mA set).
• Jumper-selectable input circuit to accept signals from a variety of sensors (i.e. sensor outputs with open collector PNP or NPN, line driver, magnetic sinewave, switch contact, etc.)

Applications:

Dynapar FV3 frequency-to-voltage converter, when used with a Dynapar encoder, converts the frequency output of the encoder to an analog signal for operating chart recorders, or for supplying velocity feedback in closed loop speed control systems.
