4114 Universal Transmitter

4114 Universal Transmitter

Quick Overview

The 4114 is a programmable universal transmitter suitable for Thermocouple, RTD, Resistance, mV, mA or Voltage inputs and 3.75 kVAC galvanic isolation. The unit converts the input into a configurable 0(4)-20mA or 0-10V output that is proportional and linear to the value of the input. Units are available with the 4510 programming display or the 4511 Modbus communications/programming interface. Universal AC or DC power supply.
View Options



  • Linearised, electronic temperature measurement with RTD or TC sensor.
  • Conversion of linear resistance variation to a standard analogue current / voltage signal, i.e. from solenoids and butterfly valves or linear movements with attached potentiometer.
  • Power supply and signal isolator for 2-wire transmitters.
  • Process control with standard analogue output.
  • Galvanic separation of analogue signals and measurement of floating signals.
  • The 4114 is designed according to strict safety requirements and is thus suitable for application in SIL 2 installations.


  • Input for RTD, Thermocouples, Ohm, potentiometer, mA, mV and V
  • 2-wire supply > 16 V
  • FM-approved for installation in Div. 2
  • Output: 0(4)-20mA, 20-0(4)mA or 0-10V or 10-0V
  • Universal AC or DC supply
  • Programmable by way of detachable display front (4510), process calibration, signal simulation, password protection, error diagnostics and help text available in several languages.
  • Modbus RTU output via 4511 detachable display


4510 Display/Programming Interface


  • Communications interface for modification of operational parameters in 4114.
  • Can be moved from one 4114 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


  • 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


4512 Bluetooth Communications Interface

Application:PR 4512 Bluetooth Communication Interface

  • Program devices via Bluetooth using an iOS/Android device running the free PPS app (PR Process Supervisor).
  • Use PPS data for preventive maintenance.
  • All logged data can be exported in .csv format, for advanced data analysis off-site.
  • On-site analysis of real-time process data on an iOS/Android compatible device.
  • Off-site analysis of historic process data on a PC using PReset.

Technical characteristics:

  • PR 4512 runs Bluetooth 4.2, and requires a smart device with 4.0 or newer.
  • PPS is compatible with iOS and Android devices.
  • The PR 4512 automatically detects the device setting on the connected PR 4000 and 9000 device.
  • An internal battery energizes the 4512 real-time clock for at least 2 years, should the 4512 remain de-energized.
  • Typical data logging capacity is more than 30 days at 1 second intervals.
  • Easy to read dot matrix LCD display.
  • Fast pairing or safe pairing via two-factor authentication.


Android App for 4512 Interface
