The functions below are tied directly to this model's official technical record.
Onboard field I/O
The main unit provides 16 digital inputs, 10 relay outputs and up to four high-speed counters.
Temperature and analogue signals
One thermocouple and one analogue input can be extended with temperature, analogue and digital I/O.
Connectivity and commissioning
Ethernet, RS485, USB download and USB storage support the SKTOOL7.1 workflow.
I/O architecture
Plan the main unit and expansion together
Separate what is onboard from what requires a plug-in module before preparing the panel and bill of materials.
Main unit16 DI · 10 relay outputs · 1 thermocouple · 1 analogue input · up to 4 high-speed counters
Plug-in expansionUp to 16 I/O points · 8 temperature inputs · 8 AI · 8 AO
4G/Wi-Fi is specified as compatible module support, not as an integrated connection. Confirm the module and carrier infrastructure in the project quotation.
Examine the product from every side
Review the front panel, rear I/O and connector layout before planning the enclosure.
Dimensions and panel cut-out
Use the official drawing together with the nominal catalogue values when planning panel machining and terminal access.
Specifications arranged for engineering review
All source-qualified values are visible by topic; no decision-critical data is hidden behind an expandable panel.
