Choosing between the N-TRON 708TX and the Cisco IE-3000-8TC comes down to whether you want to spend less or carry more capability. The price spread between the two is USD 90.01: the N-TRON at USD 159.99 and the Cisco at USD 250.00. That gap tracks a difference in condition, port count, and industrial feature set.
Quick Verdict
The N-TRON 708TX is the lower-price choice: an 8-port, 10-30VDC switch in New - Open box condition. The Cisco IE-3000-8TC is the higher-capacity choice: a used 16-port switch with dual DC inputs, an alarm relay, a console port, and a hazardous-location rating. Pick N-TRON when the lower price and open-box condition fit; pick Cisco when you need more ports and broader industrial features.

Product Notes
N-TRON 708TX

With an Ethernet/IP communication standard, black cable color, and a 10-30VDC input range, the N-TRON 708TX is a straightforward option for an 8-port industrial network switch. It is a New - Open box unit originally removed from an industrial environment. Choose it when you want the lower price in this pairing and a switch designed around a 10-30VDC supply. The one catch is the included contents: the description says only what is shown in the photos is included, with no additional accessories, cables, or power supplies unless pictured.
Cisco IE-3000-8TC

The Cisco IE-3000-8TC is a used, Grade B unit that may have slight scratches from handling, with plastic covering retained on one side. It accepts 18-60V DC power and is rated for -40°C to +60°C operating temperatures, which points to demanding environments. Choose it when you want 16 ports and the dual DC inputs, alarm relay, console port, and hazardous-location rating that come with this model. The limitation is condition and contents: it is used and the description says it does not come with accessories, so rely on the photos for what is included.
Final Choice by Use Case
If your priority is the lower price and an 8-port new open-box switch, the N-TRON 708TX is the straightforward pick. If you need 16 ports, dual DC inputs, an alarm relay, a console port, and a hazardous-location rating for a more demanding network, the Cisco IE-3000-8TC earns the extra USD 90.01.
