Application-Specific FAQ
Q: Is the 5094-OB16 compatible with ControlLogix 5580 controllers?
A: Yes. The Flex 5000 platform communicates over EtherNet/IP and is fully compatible with ControlLogix 5580, 5570, CompactLogix 5380, and 5480 controllers running Studio 5000 v24 or later.
Q: Can I mix 5094-OB16 with analog modules on the same adapter?
A: Yes. Flex 5000 supports mixed I/O configurations — digital, analog, and specialty modules can coexist on a single 5094-AENSFR adapter up to the backplane power budget.
Q: What is the maximum cable length for field wiring?
A: Rockwell recommends keeping field wiring under 30 m (100 ft) for 24VDC discrete I/O to minimize voltage drop and noise susceptibility. Shielded cable is recommended in high-EMI environments.
Q: Does this module support electronic fusing or short-circuit protection?
A: The 5094-OB16 provides per-channel overcurrent detection with diagnostic reporting. External fusing per Rockwell’s wiring diagram is still recommended for field device protection.
Q: Is a new or refurbished unit available?
A: Konmask.com stocks both new-in-box and tested surplus units. Contact us to confirm current availability and condition grade.
