The FB1200 can operate in an unprotected outdoor environment. Wiring for I/O, communications,
and power enters the enclosure through the four conduit fittings with appropriate protective seals
and connects to the terminal plate.
The front end cap (cover) provides a viewing window for the HMI module. You can access the
terminal plate by removing the rear end cap (cover).
The FB1200 has North American certification for Class I Division 1 Groups C and D (explosion proof)
and Class I Division 2 Groups A, B, C and D (non-incendive) hazardous locations or non-hazardous
locations. See Appendix A and Appendix B for more information.
The FB1200 has European certification for EExd Zone 1 (flame proof) and EExd Zone 2 (non-
sparking) hazardous locations or non-hazardous locations. See Appendix C and Appendix D for more
information.
Details on certification information are included on the data plate screwed to the top of the
enclosure.
1.6 I/O
The flow computer comes with base I/O from both the CPU and the built-in multi-variable (MV)
sensor.
Base I/O consists of:



An optional 6-channel expansion I/O board includes:
