Description

Applications

• Fast < 20 ms response time for measuring signals produced by torque, position, current & acceleration sensors.
• User configurable bipolar or unipolar I/O means the 4184 is suitable for nearly any DC voltage or current conversion.
• Freely programmable between ±300vDC and ±100mA.
• The excitation source allows measurement of a 2-wire or 3-wire transmitter, or a potentiometer.
• Converts narrow bipolar inputs to wide bipolar or unipolar outputs, e.g. ±1 volt input = ±10 volt or 4…20 mA output.
• Configurable input limits control the output value for increased safety.
• ±20vDC buffered voltage output for controlling devices like the PVG 32 valve (6-18vDC).

Features

• Measures uni/bipolar ±300V and ±100mA input ranges
• Generates uni/bipolar ±10V and ±23mA output ranges
• Universal 21.6-253vAC or 19.2-300vDC power supply
• The 4184 measures standard input ranges and can be freely configured to customer defined input range.
• Configurable input limits control the output value for increased safety

4510 Display/Programming Interface

Application:

• Communications interface for modification of operational parameters in 4184.
• Can be moved from one 4184 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

4512 Bluetooth Communications Interface

Application:

• 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.
