9-Port Gigabit Industrial Ethernet Switch
Model SP-CM-003 · our reference
9-port light-managed DIN-rail switch with sub-20 ms ring recovery and -40 to +85 C range
Overview
The SP-CM-003 is a low-power industrial Ethernet switch with 3 fast Ethernet fiber/RJ45 ports and 6 10/100Base-T(X) copper ports for building fiber rings with a spare uplink port. It supports DT-Ring, DRP/DHP, VLAN and SNMP management with ring recovery times below 20 ms. A fanless metal housing rated IP40 and EMC level 4 approvals make it suitable for wind power, distribution networks, transportation and oil and gas sites.
Key highlights
- 3 fast Ethernet fiber/RJ45 optional ports plus 6 10/100Base-T(X) ports
- DRP/DHP ring recovery under 20 ms; DT-Ring/DT-VLAN under 50 ms
- 8K MAC table, 1 Mbit packet buffer and 1.4 Mpps forwarding rate
- Dual redundant power inputs and under 8.1 W power consumption
- Fanless metal housing with IP40 protection and 5-year warranty
- Certified to CE, FCC, UL508 and Class I Div 2
