- Description
The Siemens 6ES7963-2AA10-0AA0 is the IF963-TTY interface module for the SIMATIC S7-400 CP441, adding a 20 mA current-loop (TTY) physical layer for point-to-point coupling. It reaches up to 1000 m of cable at 9600 bps and up to 19.2 kbit/s transmission rate, drawing 15 mA from 3.3 V and 23 mA from 24 V at 0.6 W typical power loss.

Selection Notes
Pick IF963-TTY when the PTP link has to cover long cable runs (up to 1000 m) or noisy wiring paths, since a current loop is inherently more tolerant of line noise than RS232. The trade-off against IF963-RS232 is speed, capped at 19.2 kbit/s instead of 115.2 kbit/s; the IF963-X27 (RS422/RS485) keeps both long reach and the higher rate if the wiring supports it.
