Product Recommendation | Solidot C Series Industrial Ethernet Switch Selection Guide

Solidot C Series unmanaged industrial Ethernet switches are suitable for industrial scenarios such as small device networking, single-machine communication, and point-to-point transmission. There are 8 models in total, covering 100M (HUP) and Gigabit (GUP), 5‑port and 8‑port, standard and PoE power supply combinations. No configuration is required; power on and work.

Core Parameters Overview
Unified design and performance indicators across the series are as follows.

I. How to choose between 100M and Gigabit?
The 100M models (SW4‑HUP05C / SW4‑HUP08C) cover the communication needs of conventional industrial control devices such as PLCs, inverters, and HMIs – these devices typically have communication bandwidth not exceeding 10Mbps, so 100M switches are sufficient. Gigabit models (SW4‑GUP05C / SW4‑GUP08C) are intended for scenarios requiring higher bandwidth, such as vision systems, large‑volume data acquisition, or uplink aggregation. The main differences between the two are listed.

II. How to choose between standard and PoE?
The standard and PoE models of the C series are identical in industrial‑grade design (wide temperature, IP40, dual power redundancy, EMC), differing only in power supply method. PoE models cover all combinations of port count (5/8) and speed (100M/Gigabit) available in the standard version. Selection requires only two steps: first determine port count and speed based on the number of devices, then decide whether the terminal requires PoE power supply.
