SIEMENS 6DR4004-1M Positioner Module

The SIEMENS 6DR4004-1M is a manometer manifold (pressure gauge accessory) used with the SIPART PS2 electropneumatic valve positioner system, not a PLC or electronic control module.

Product Information

• Brand: Siemens
• Series: SIPART PS2
• Part Number: 6DR4004-1M
• Type: Manometer / Pressure Gauge Manifold (positioner accessory)

  • Chamber pressure up to ~6 bar
• System role: Retrofit accessory for positioner diagnostics and tuning

What it actually is

This is a mechanical pressure monitoring accessory, meaning:

• It is mounted on a SIPART PS2 positioner
• It shows air pressure values inside the actuator system
• It helps technicians adjust and diagnose valve performance

It does NOT:

• Perform control logic ❌
• Send digital signals ❌
• Act as PLC or electronic module ❌
• Control valves directly ❌

System Role (Simple)

Controller / PLC
→ SIPART PS2 positioner
→ pneumatic valve actuator
→ 6DR4004-1M manifold (pressure gauges)
→ visual pressure monitoring for tuning & maintenance

Key Features

• Dual pressure indication (supply + chamber)
• Designed for SIPART PS2 positioners
• Retrofit installation (easy add-on)
• Improves maintenance visibility and calibration
• Mechanical gauge-based (no electronics required for function)

Typical Applications

• Chemical plants valve control systems
• Oil & gas pipelines
• Power plant pneumatic valve systems
• Industrial process control valves
• Flow control / pressure regulation systems

Important Notes

• Not a PLC ❌
• Not a control module ❌
• Not an I/O module ❌
• Not a positioner CPU ❌
• It is a pressure gauge accessory for SIPART PS2 valve positioners ✔

Precautions

• Only compatible with SIPART PS2 system design
• Pneumatic connection must be correctly sealed (leak risk)
• Overpressure beyond rated scale can damage gauge
• Installation should be done by instrument technician
• Used for monitoring only, not control
