PR 4184 Bi-Polar DC Transmitter
  • PR 4184 Bi-Polar DC Transmitter

4184 Universal Uni/Bi-Polar Signal Transmitter

2-3 Weeks

Quick Overview

The 4184 is a programmable universal transmitter suitable for converting uni/bi-polar DC voltage or current inputs to uni-bi-polar DC outputs. The unit is capable of measuring DC voltages from -300V to +300V and DC currents from -100mA to +100mV. Units are available with the 4501 programming display or the 4511 Modbus communications/programming interface. Universal AC or DC power supply.

Details

Applications

  • Fast < 20 ms response time for measuring signals produced by torque, position, current & acceleration sensors.
  • User configurable bipolar or unipolar I/O means the 4184 is suitable for nearly any DC voltage or current conversion.
  • Freely programmable between ±300vDC and ±100mA.
  • The excitation source allows measurement of a 2-wire or 3-wire transmitter, or a potentiometer.
  • Converts narrow bipolar inputs to wide bipolar or unipolar outputs, e.g. ±1 volt input = ±10 volt or 4...20 mA output.
  • Configurable input limits control the output value for increased safety.
  • ±20vDC buffered voltage output for controlling devices like the PVG 32 valve (6-18vDC).


Features

  • Measures uni/bipolar ±300V and ±100mA input ranges
  • Generates uni/bipolar ±10V and ±23mA output ranges
  • Universal 21.6-253vAC or 19.2-300vDC power supply
  • The 4184 measures standard input ranges and can be freely configured to customer defined input range.
  • Configurable input limits control the output value for increased safety

 

4501 Display / programming front

Application:

  • Communications interface for modification of operational parameters in 4179.
  • Can be moved from one 4179 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.

 

 

4511 Modbus Communications Interface

Application:

  • The 4511 detachable display adds Modbus RTU RS485 serial communications to all current and future 4000/9000 series units
  • All individual unit operating parameters can easily and quickly be configured by using the Modbus communication or by using the front display menu
  • The 4511 display can be used to read the process signal, simulate the output signal, indicate sensor errors and internal device errors


Technical characteristics:

  • 4511 has full 4501 functionality for programming and display
  • RS485 Modbus RTU protocol
  • Multi-drop half-duplex connection via shielded RJ45 connector on top of module
  • Modbus parameters such as address, baud rate, stop bit(s) and parity bits are configured from, and stored on, the 4511 interface
  • 2.5kVAC galvanic isolation between serial wiring and 4000/9000 units


If required, Omni Instruments will program a 4184, 4501 or 4511 to your specific requirements. Please contact us for details.
