ETHERNET / Fast ETHERNET / GIGA ETHERNET-Switch compliant to IEEE 802.3
- Modular, managed, industrial Switch for DIN hat rail
- Store-and-Forward-Switching
- Software Layer 2 Professional
- Fanless design
- 28 Ports via media moduls, 3 slots integrated in the back panel (8 ports fast ethernet, 4 ports gigabit ethernet), 2 additional slots via MB- 2T expansion backplane ( 8 ports)
- 4 Ports 10/100/1000
- 24 Ports 10/100

Further interfaces
- two different connectors for power supply and alarm relay
1st. pluggable terminal block, 4-pin connector with power supply1 + Relay1
2nd pluggable terminal block, 4-pin connector with power supply2 + Relay2
advantage for the customer, although disconnect one connector, the switch still works
- V.24 interface, 1 x RJ11
- USB 1.1 interface for external flash memory (ACA 21-USB)
-SD slot for auto-configuration adapter ACA31 (SD card)
