Application

  • The detachable 4511 display adds Modbus RTU RS-485 serial communications to all current and future PR Electronics 4000 and 9000 units.
  • The unit converts a wide array of sensors and analog device signals measured by the PR 4000 series, like uni- and bipolar mA and voltage signals, potentiometer, Linear Resistance, RTD, and TC, to a Modbus communication line signal.
  • When mounted on a PR 9000 series, any signal coming from or going to EX classified area, like AI, AO, DI, and DO signals, can be converted to a Modbus network.
  • PR 4511 can easily and quickly configure all individual unit operating parameters using the Modbus communication or the front display menu.
  • The easily readable 4511 display can be used to read the process signal, simulate the output signal, and indicate sensor errors and internal device errors.
  • The 4511 can be moved from one device to another. The individual system 3000 / 4000 / 9000 device configuration of a transmitter can be saved and downloaded to subsequent transmitters.

Technical characteristics

  • 4511 has complete functionality for unit programming, process signal monitoring, and diagnostics handling.
  • Multidrop half-duplex connection via shielded RJ45 connector.
  • High safe galvanic isolation of 2.5 kVAC between the serial wiring and the connected system 4000 / 9000 units.
  • Modbus parameters such as station address, baud rate, stop bit(s), and parity bit are configured from the 4511 display, which also stores parameters.

Mounting / installation / programming

  • Mounting in Zone 2 / Div 2.
  • All configuration data from a PR 3000 / 4000 / 9000 device can be transferred to a PC using PR 4590.
  • A user-defined password can protect programmed parameters.
  • When mounted on devices installed upside down, a menu item allows the display to rotate 180° and the up/down buttons to switch functions.
