The IC086SLN080 is an 8-port unmanaged industrial Ethernet switch in Emerson's PACSystems portfolio — the largest all-copper unmanaged model in the IC086 family. With eight 10/100Base-T(X) RJ45 ports, store-and-forward switching, and auto MDI/MDIX on every port, it delivers plug-and-play connectivity for small machine-level networks where managed switch features such as VLANs, SNMP monitoring, and ring redundancy are unnecessary.

When is an unmanaged switch sufficient?

Managed switches bring VLAN segmentation, SNMP diagnostics, and ring redundancy — all valuable in plant-wide architectures. But many machine-level networks are simple: a controller, an HMI, a few drives, and an uplink to the plant backbone. In these scenarios, an unmanaged switch saves cost, eliminates configuration steps, and reduces points of failure. No IP address to assign, no firmware to maintain, no VLAN database to audit. The SLN080 adds value in its industrial hardening — -40°C to +70°C fanless operation, dual redundant 12–48 VDC power inputs with reverse-polarity protection, and IP30 enclosure — which consumer-grade unmanaged switches cannot match.

How does the SLN080 compare to the SLN050?

The SLN050 provides 5×10/100Base-T(X) ports in an ultra-compact 26.1×70×95 mm, 205 g form factor — ideal for the smallest machine-mounted enclosures. The SLN080 extends this to 8 ports, housed in a larger 26.1×94.9×144.3 mm, 391 g chassis. The additional three ports eliminate the need for a second switch when a machine has more than five Ethernet nodes — a single SLN080 replaces two SLN050 units plus the inter-switch cable, reducing component count and potential failure points. Both switches share the same -40°C to +70°C temperature rating, IP30 enclosure, dual DC power inputs, and 5-year warranty.
