VEICHI VH Remote Expansion / Remote I/O
EtherCAT and PROFINET remote I/O drops, 125 us cycle
Remote I/O for when the signals are a long way from the controller. A VH-RTU-ECT or VH-RTU-PN head takes up to sixteen modules and drops them onto EtherCAT or PROFINET, cutting the cabinet space needed by roughly two thirds against running everything back to a central rack.
- Communication heads
- VH-RTU-ECT (EtherCAT), VH-RTU-PN (PROFINET v2.3 RT)
- Backplane
- VBUS at 100 Mbps
- Transfer cycle
- 125 us minimum on backplane; 1 ms minimum on PROFINET
- Capacity
- Up to 16 I/O and special modules per drop
- Compatible
- VH300, VH500, VH600
Around two-thirds less cabinet space than a central rack
EtherCAT IN/OUT ports for daisy-chained slaves
D-BUS with metal plates both sides for mechanical robustness
Modules configured per drop to suit the location
Lower-cost route to a distributed I/O architecture
Typical applications
Distributed machine and line controlLong cable runs to remote plantRetrofitting I/O onto an existing EtherCAT or PROFINET network
