The DigiComm ISD-204 industrial switches offer 4 x Gigabit Ethernet and 2 Gigabit fiber ports. The fiber ports can be equipped with any SFP modules for individual adaptation to your own network and thus ensure a wide range of applications.

The support of 10/100/1000 Base-T(X) and 100/1000 Base-F(X) Gigabit ports makes the DigiComm ISD-204 suitable for use in complex high-speed networks, which are optimized for high data throughputs or also low latency times.

This switch has a redundant DC power supply of 12-57 VDC, an IP30 protected full metal housing and is suitable for DIN rail mounting.

Depending on the requirement profile, the DigiComm ISD series is available in a manageable Layer 2 or unmanaged version.
The managed version supports all important and security relevant protocol standards with VLAN, SNMP v1/v2 and v3, HTTPS, IGMP v1/v2 and v3.
