PR 4179 Universal AC/DC Transmitter
  • PR 4179 Universal AC/DC Transmitter

4179 Universal AC/DC Transmitter

Quick Overview

The 4179 is a programmable universal transmitter suitable for converting AC voltage or current to a standard DC voltage and current signal with 2.3kV isolation. The unit is capable of measuring up to 0 to 5A RMS and 0-300V RMS directly with a narrow 500mA RMS and 500mV RMS span. Units are available with the 4501 programming display or the 4511 Modbus communications/programming interface. Universal AC or DC power supply.

Details

Applications

  • 0 to 5A AC RMS range ideal for accurately measuring a typical current transformer
  • 0 to 300vAC RMS range allows accurate supply voltage monitoring
  • The 4179 measures standard input ranges and can be freely configured to customer defined input range.
  • Can convert narrow AC current/voltage inputs to wide bipolar or unipolar outputs.
  • Configurable input limits control the output value for increased safety


Features

  • The latest analog and digital techniques used to obtain the maximum accuracy and immunity to interference.
  • Possibility of output safety feedback by selecting S 4-20 mA output.
  • The current output can drive up to 800 Ohms, with an adjustable response time of 0-60.0 seconds.
  • Exceptional mA output load stability of <0.001% of span / 100 Ohm.
  • Meets the NAMUR NE21 recommendations, ensuring high accuracy in harsh EMC environments.
  • Meets the NAMUR NE43 recommendations, allowing the control system to easily detect an input error.
  • Each unit is tested to a high 2.3 kVAC, 3-port galvanic isolation level.
  • Excellent signal to noise ratio of > 60 dB.
  • Output: Active unipolar or bipolar ±20mA, 2-wire 0-20mA, bipolar ±10V with direct or inverted action
  • Universal AC or DC supply
  • Programmable by way of detachable 4501 display front
  • Modbus RTU output via 4511 deteachable display

 

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 4179, 4501 or 4511 to your specific requirements. Please contact us for details.
