PR 4511 has full 4501 functionality for unit programming, process signal monitoring, and diagnostics handling
Modbus RTU protocol is supported using a serial RS-485 communication wiring
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 address, baud rate, stop bit(s), and parity bit are configured from the 4511 display, which also stores parameters
Applications for PR 4511
The 4511 detachable display adds Modbus RTU RS-485 serial communications to all current and future 4000/9000 units
The unit converts a wide array of sensors and analog device signals measured by the system 4000 like uni- and bipolar mA and voltage signals, potentiometer, Lin. R, RTD, and TC, to a Modbus communication line signal
When mounted on a system 9000 device any signal coming from or going to I.S. classified area, like AI, AO, DI, and DO signals, can be converted to a Modbus network
All individual unit operating parameters can easily and quickly be configured by using the Modbus communication or by using the front display menu
The easily readable 4511 display can be used to read the process signal, simulate the output signal, indicate sensor errors and internal device errors
Mounting, Installation, and Programming
Mounting in Zone 2 / Div 2
The 4511 can be moved from one device to another
The individual system 4000/9000 unit configuration of the first device can be saved and downloaded to subsequent devices
Programmed parameters can be protected by a user-defined password
When mounted on devices that are installed upside down, a menu item allows the display on the 4511 to be rotated 180o and the up/down buttons to switch function
