Moxa NPort P5150A 1-Port PoE Serial Device Server
Description
How the NPort P5150A puts serial devices on Ethernet
NPort P5150A is listed by Moxa as: 1-port RS-232/422/485 PoE device server, 0 to 60°C operating temperature. A single-port serial device server that can be powered through Power over Ethernet or from a DC adapter, so a serial instrument can be connected with one network cable.
On the datasheet side, the power input is 12 to 48 VDC (supplied by power adapter); 48 VDC (supplied by PoE); operating temperature is 0 to 60°C (32 to 140°F); dimensions are 100 x 111 x 26 mm (3.94 x 4.37 x 1.02 in); weight is 300 g (0.66 lb).
Standards and approvals printed for this model include safety standard EN 62368-1; UL 60950-1. Approvals can differ between variants of a series, so check the one on the exact order code.

Selecting the right variant
It fits retrofits where a power outlet is not at hand but a PoE switch port is, for example metering points, gate controllers and laboratory instruments. The port is DB9 male and accepts RS-232, RS-422 or RS-485.
On the practical side, the housing is metal; the stated MTBF is 2,231,530 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 that the PoE switch or injector provides the 48 VDC the specification lists, or that an adapter in the 12 to 48 VDC range is available, and the cable type for the serial device before you place an order. Seven Star LLC supplies as an independent company and prices against the precise code requested.

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.
