Replacement & Compatibility FAQ
Q: Can I replace the 1783-US16T with a managed switch?
A: Yes, but managed switches require additional configuration. The Stratix 5700 (1783-MS10T) is the recommended managed upgrade path within the AB ecosystem.
Q: Is the 1783-US16T compatible with Siemens PROFINET devices?
A: The switch is protocol-agnostic at Layer 2 and will pass PROFINET frames, but it is not PROFINET-certified. For PROFINET topologies, use a SCALANCE switch.
Q: What is the difference between 1783-US16T and 1783-US16TG?
A: The 1783-US16TG adds Gigabit (1000BASE-T) ports. If your devices support Gigabit, the TG variant offers higher throughput headroom.
Q: Can this switch be used in a Class I Division 2 hazardous location?
A: Yes, the 1783-US16T carries Class I Div 2 / ATEX Zone 2 certification when installed per Rockwell’s installation guidelines.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes, CoC is available upon request at no additional charge.
