It is used in SIMADYN D digital control configurations to provide an extra, independent V.24 channel for serial data exchange between the SIMADYN D controller and external devices such as programming consoles, diagnostic tools, modems, or other automation equipment. The V.24 interface supports standard RS-232 signaling, including data lines TXD and RXD and common control lines CTS, RTS, DTR, and DCD, enabling proper handshaking and remote signaling. The 6DD1688-1AB0 part is documented in Siemens hardware references as the SS2 submodule for SS4 communications, designed to plug into the SS4-based configuration without altering the core SS4 functionality; it is intended for use in appropriate SIMADYN D rack configurations with SS4 modules.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268260057322,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-017.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6dd1688-1ab0-v-24-interface-submodule","provider":"GTG Hardware","version":"1.0","type":"link"}
