How to choose
- Create an I/O schedule with each digital, analogue, temperature, encoder and relay point before choosing the coupler and modules.
- Confirm the controller-side fieldbus, update time, redundancy and diagnostics expected from the remote I/O station.
- Review the DC field power, module derating, panel width, terminal style, shielding and environmental conditions for each cabinet.
Compatible with
- PLC or industrial controller using the selected PROFINET or EtherCAT coupler
- Digital, analog, PT100, K-type thermocouple and encoder expansion modules selected from the I/O schedule
- Control panels after the ordered coupler supply and grounding path are checked
Typical package
- One PROFINET or EtherCAT bus coupler for the selected controller network
- Expansion modules matched line by line to the project I/O schedule
- DIN-rail power, terminals, shielding and panel wiring selected by the panel builder
- I/O map, module order and acceptance checklist for the quoted configuration
Applications
Use a distributed remote I/O station when field signals need to be collected close to the machine or cabinet and returned to a PLC over industrial Ethernet. Select one controller-side coupler first, then build the station from the actual I/O schedule; PROFINET and EtherCAT are separate configurations rather than simultaneous protocols.
- Distributed machine I/O returned to a central PLC
- Cabinet expansion where long home-run signal wiring is impractical
- Mixed digital, analog, temperature and encoder point collection
What to include in your quote request
- PLC / controller and required fieldbus
- Complete I/O schedule and channel count

Frequently asked questions
Can one coupler run PROFINET and EtherCAT at the same time?
No. PROFINET and EtherCAT are separate coupler configurations. Select the coupler that matches the PLC network, then build the station from the required I/O modules.
Which I/O module types are covered by the reviewed family?
The reviewed family includes switching, analog, PT100, K-type thermocouple and encoder expansion modules. Exact channel counts and module order are taken from the project I/O schedule.
What should I provide when requesting a quote for the Distributed Remote I/O System?
PLC / controller and required fieldbus; Complete I/O schedule and channel count; Signal ranges, sensor types and isolation needs; Update time, diagnostics and redundancy
Where can I compare available model options?
Open the Industrial Monitoring Hardware Catalog linked on this page. It lists audited SG-coded selections; the ordered configuration is confirmed in the quotation.
Will it work with my existing system?
Compatibility is reviewed against your field signals, protocols and upstream platform. Typical pairings include PLC or industrial controller using the selected PROFINET or EtherCAT coupler, Digital, analog, PT100, K-type thermocouple and encoder expansion modules selected from the I/O schedule, Control panels after the ordered coupler supply and grounding path are checked.
