|---|---|---|---|---|---|
| Explanation: |
Platform UE20 - UE20 I/O platform; this breakdown covers the two listed UE20 couplers |
Module RTU - Bus coupler |
Protocol EC - EtherCAT |
UE20-RTU-EC and UE20-RTU-PN connect a modular I/O station to EtherCAT or PROFINET respectively. Each supports up to 32 expansion modules and 1024 bytes of process data. Two RJ45 ports provide the network connection, while spring terminals handle power wiring.
