Description

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
