Selection Guide
Use the following decision framework to determine if the 6DR4004-8J is the right module for your application:
- Identify your positioner model — Confirm you have a SIPART PS2 series unit (6DR5xxx).
- Check the plug-in slot — Verify the LY slot is available and unoccupied in your positioner housing.
- Confirm communication protocol — Ensure the module variant matches your fieldbus or HART configuration.
- Review hazardous area requirements — If installed in Ex zones, confirm ATEX/IECEx certification of the specific variant.
- Assess replacement vs. upgrade — If replacing a failed module, match the original part number exactly. If upgrading, consult the SIEMENS SIPART PS2 accessory catalog.
- Contact Konmask for sourcing — Provide your positioner serial number and existing module part number for fastest fulfillment.
