TB20 Communication module – RS-232 serial interface 1 SI, RS-232/RS-422/RS-485

Part of the Helmholz decentralized fieldbus I/O system – TB20.?The other communication device can be a serial module or any other device that supports the aforementioned standard.

This serial module supports both the ASCII and 3964R protocols. This makes it possible to integrate downstream devices (e.g., printers, laser scanners, etc.) into higher-level bus systems and networks in an automation system, or to communicate with other system parts.
