SIEMENS FDK:085U1039 Sensor Module

SIEMENS FDK:085U1039 / FDK:085U1039 Sensor / Keypad Display Unit

 

 

The SIEMENS FDK:085U1039 is a keypad / display unit for SITRANS MAG5000 / MAG6000 flow transmitters, used in industrial flow measurement systems.

Product Information

• Brand: Siemens
• Part Number: FDK:085U1039
• Type: Keypad / Display / HMI interface unit
• System: SITRANS MAG5000 / MAG6000 flow meter series
• Function: Local operation, parameter setting, and display of flow data
• Protection rating: IP67 (dustproof + water resistant)
• Keys: 6-button membrane keypad
• Installation: Mounted on flow transmitter housing

What it actually is

This is not a sensor and not a PLC module.

It is a human-machine interface (HMI) for a flow meter, meaning:

• Used to view flow data locally
• Used to configure flow transmitter parameters
• Used for diagnostics and calibration
• Works only together with MAG5000/MAG6000 transmitter

It does NOT:

• Measure flow directly ❌
• Act as controller ❌
• Communicate as PLC module ❌
• Work standalone ❌

System Role (Simple)

Flow sensor body (MAG meter)
→ transmitter (MAG5000 / MAG6000)
→ FDK:085U1039 keypad/display
→ operator sets parameters / reads values

So it acts like a “control screen for a flow meter system”.

Key Features

• 6-key membrane operation panel
• IP67 protection (harsh industrial environments)
• Displays flow measurement values
• Used for parameter configuration and diagnostics
• Plug-in interface to MAG transmitter
• Designed for process instrumentation systems

Typical Applications

• Water treatment plants
• Chemical processing flow monitoring
• Oil & gas flow measurement systems
• Industrial pipeline flow control
• Process automation (DCS/SCADA systems)

Important Notes

• Not a PLC ❌
• Not a sensor ❌
• Not a communication module ❌
• It is a flow meter display/keypad interface unit ✔
• Must be used with MAG5000 / MAG6000 transmitter

Precautions

• Only compatible with Siemens SITRANS MAG system
• Improper mounting can break sealing (IP67 protection loss)
• Cannot operate without transmitter unit
• Sensitive membrane keypad (avoid mechanical damage)
• Used mainly in process instrumentation environments
