4222 Universal I/f Converter

Quick Overview

The 4222 is a universal current/voltage to frequency converter. The 4222 accepts RTD, TC, Ohm, potentiometer, mA and V inputs and produces a frequency output between 0.001 and 25,000 Hz. The unit can be programmed via the detachable 4501 display front.

Details

Applications

  • Linearised, electronic temperature measurement with RTD or TC sensor.
  • Conversion of linear resistance variation to a frequency signal, e.g. from solenoids and butterfly valves or linear movements with attached potentiometer.
  • Power supply and signal isolator for 2-wire transmitters.
  • Process control by way of a frequency signal transmitted to e.g. a PLC or a process computer.
  • Galvanic separation and conversion of analogue signals to frequency signals.

Features

  • Input for RTD, TC, Ohm, potentiometer, mA and V
  • Frequency output NPN, PNP and TTL
  • Generates frequencies from 0.001 - 25000 Hz
  • 2-wire supply > 16 V
  • Universal AC or DC supply
  • Programmable via detachable display front (4501)

PR 4501 Display / programming front

Application:

  • Communications interface for modification of operational parameters in 4222.
  • Can be moved from one 4222 module to another and download the configuration of the first converter to subsequent converters.
  • Fixed display for readout of process data and status

Technical characteristics:

  • LCD display with 4 lines; line 1 (H = 5.57 mm) shows input signal, line 2 (H = 3.33 mm) shows units. Line 3 alternates between digital output value and scaling (kHz, Hz, mHz, P/m, P/h, P/d) or shows TAG no. Line 4 shows tendency readout for the input signal and communication status.
  • Programming access can be blocked by assigning a password. The password is saved in the converter in order to ensure a high degree of protection against unauthorised modifications to the configuration.


If required, Omni Instruments will program a 4222 to your specific requirements. Please contact us for details.
