HIRSCHMANN MS20 Rack Switch 4x MM2-4TX1 Modules

The Hirschmann MS20 rack-mount modular switch comes with four MM2-4TX1 media modules and provides high-density Fast Ethernet connectivity for industrial networks that need it. This setup gives the MS20 MICE platform the most flexibility by giving it 16 x 10/100BASE-TX RJ45 ports to connect many PLCs, HMIs, SSDs, and field devices in one small box. Designed to work 24 hours a day, 7 days a week in tough conditions, its fanless design, strong enclosure, and wide temperature range make sure that it works all the time in control cabinets all over the world.

This 4-module MS20 arrangement is great for expanding automation systems since it provides managed switching features like VLANs, QoS, and redundancy. It is suitable for process control, machinery, and infrastructure applications that need a dependable Ethernet backbone expansion with a lot of ports.

MS20 Base Switch

Applications:

1) PLC and I/O networking with a high port count for SCADA systems and large-scale factory automation lines.

2) Copper Ethernet drops are utilized to connect valves, sensors, and DCS panels in process plant expansions.

3) Compact control enclosures are required by OEM machinery manufacturers for the connection of 16 or more devices.

4) Reliable field device aggregation to central controllers is contingent upon the availability of transportation infrastructure, such as airports and rail.

5) Robust, high-density Ethernet ports are necessary for marine/offshore engine rooms and automation panels.
