Description
The GE/MTL F809F-Plus, referenced by certificate MTL13ATEXF809FPLUSX, is an 8-spur fieldbus diagnostic module designed for FOUNDATION Fieldbus H1 and PROFIBUS PA networks. It mounts on a DIN rail and provides individual spur short-circuit protection, power conditioning, and real-time segment diagnostics via an integrated LCD display.
This unit eliminates the need for hand-held diagnostic tools on routine checks by displaying per-spur current, segment voltage, and communication status at a glance. The ATEX Ex nA (non-sparking) certification permits installation in Zone 2 hazardous areas without an expensive flameproof enclosure . This is the “Plus” variant, offering enhanced diagnostics over the base F809F model.
Frequently Asked Questions
Q: What exactly is the MTL13ATEXF809FPLUSX—is it the module or just a certificate?
A: Good catch. The string “MTL13ATEXF809FPLUSX” is the ATEX certificate number assigned to the F809F-Plus product . In procurement systems, this full string often becomes the line item part number to ensure you receive the unit with the correct regional approval. You are ordering the F809F-Plus diagnostic module with active ATEX certification.
Q: Does this unit require an external power supply?
A: No. The F809F-Plus is segment-powered. It draws its operating power directly from the fieldbus trunk (18-32 VDC). You do not need to run a separate 24 VDC line to the module, but verify your power supply can handle the additional 15 mA consumption of the module’s electronics plus the 400 mA total field current budget.
Q: What does the diagnostic display actually show?
A: The 16×2 character LCD per spur cycles through key parameters. You can read:
- Spur current (mA) per device
- Segment voltage at the trunk
- Spur short-circuit indication (the module isolates that spur and flags it)
- Communication status (active traffic detected)
It saves you from walking back to the host system or clamping a multimeter on live wires.
Q: Is this module hot-swappable?
A: The F809F-Plus is not designed for true hot-swap of the module itself. You must remove segment power before unplugging the unit from the DIN rail connector. However, the spurs are hot-swappable—you can connect or disconnect field devices on individual channels without dropping the segment, provided the spur electronics are working.
