The I/O Module 16 can be remotely operated through the RS-485 connector. It provides 4 digital inputs, 4 digital outputs, and 8 flexible interfaces that can be configured as digital input or digital output. Smart Manager 4.0 is able to control up to 8 of these expansion modules through the RS-485 interface. This makes it possible to provide a total of 16 to 128 flexibly configurable digital I/Os. All I/Os are galvanically isolated according to IEC 61131-2 and support up to a maximum of 2,500 Vrms according to DIN VDE V 0884-11:2017-01. Controllable digital I/Os conform to IEC 61131-3 using free CoDeSys libraries.
The STV Electronic I/0 modules use the Raspberry Pi 3’s Smart Manager API for configuration and evaluation. Smart Manager 4.0 is also able to provide a web interface for remote configuration and status viewing. If only the I/O module’s inputs are used, no separate 24VDC power supply is required and the module can be powered directly through the Raspberry Pi DIN rail PC interface. If several I/O modules are connected via RS-485, each module is given its own address via the coding switch on the front. This allows flexible system expansions with up to 8 I/O modules for up to 128 configurable digital I/Os.
“Just like with the Raspberry Pi DIN rail PC, we offer OEMs and system integrators a robust industrial design and long-term availability of at least 10 years for the new I/O modules, too. This includes full Linux OS customization, comprehensive software and integration support, as well as continuously updated security patches. This makes our industrial open source solution extremely attractive for many edge computing tasks in building automation and industrial control technology, especially since we support all common interfaces and will also continuously add new expansion modules to our range,” explains Markus Hühn, Managing Director of STV Electronic.
The Raspberry Pi based DIN rail PC Smart Manager 4.0 has up to 2x Ethernet,
