Moxa MGate 5217I-600-T Modbus to BACnet/IP Gateway
Description
How the MGate 5217I-600-T bridges protocols
A two-port gateway that publishes Modbus RTU/ASCII and Modbus TCP data to a BACnet/IP building system, licensed for 600 points with 2 kV serial isolation and a -40 to 75 degrees C range. Moxa’s own one-line description of the MGate 5217I-600-T reads: 2-port Modbus-to-BACnet/IP gateway, 600 points, 2kV isolation, 12 to 48 VDC, 24 VAC, -40 to 75°C operating temperature.
Key figures from the Moxa page: the power input is 24 VAC; 12 to 48 VDC; operating temperature is -40 to 75°C (-40 to 167°F); dimensions are 29 x 89.2 x 118.5 mm (1.14 x 3.51 x 4.67 in); weight is 380 g (0.84 lb); the enclosure is rated IP30.
Standards and approvals printed for this model include safety standard UL 60950-1; UL 62368-1; IEC 60950-1; IEC 62368-1. Approvals can differ between variants of a series, so check the one on the exact order code.

Where it fits and what to check
It links chillers, meters, genset controllers and other Modbus equipment to a BACnet/IP building management system in HVAC and facilities projects.
On the practical side, the housing is plastic; the stated MTBF is 1,277,500 hrs; the warranty period is 5 years. Treat the MTBF as a manufacturer prediction under its stated method, not a guarantee for your site.
Please check the point count your project needs (the 5217I-1200-T carries 1200), and whether the Modbus side is serial or TCP before you place an order. Seven Star LLC supplies as an independent company and prices against the precise code requested.

About brand
Moxa is the Taiwanese maker of industrial networking equipment: Ethernet switches, serial device servers, protocol gateways, media converters, secure routers and remote I/O. It was founded in Taiwan in 1987 and started with serial communication products before moving into industrial Ethernet. It is headquartered in Taipei.
Seven Star LLC is an independent supplier in Muscat. We list Moxa switches, serial servers, gateways and converters, and supply them to control system integrators, utilities, oil and gas and building automation projects in Oman and the GCC by exact model.

The choice between switch types follows the network. An unmanaged switch simply forwards traffic and suits a small, isolated panel. A managed switch adds redundancy protocols (Moxa's Turbo Ring recovers a broken ring in milliseconds), VLANs to separate traffic, port mirroring and alarms, which a SCADA or DCS network needs. The suffix on a Moxa model also matters: "-T" means a wide operating temperature range (typically -40 to 75 °C), which is the safe choice for outdoor cabinets in the Gulf summer. "-MM-SC" or "-S-SC" means multi-mode or single-mode fibre with SC connectors.
Where Moxa products are used
In Oman and the GCC, Moxa equipment connects RTUs, PLCs, meters and protection relays in oil and gas fields, electrical substations, water and wastewater SCADA, transport, and building and energy management systems.
Ordering Moxa products: what we need
Send the complete model including all suffixes (for example EDS-508A-MM-SC-T), the quantity, and for fibre models the fibre type and distance. For gateways, tell us which two protocols need to be linked.
