Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The board exposes a three-position screw terminal block for RS485 wiring: Data+ (A), Data- (B), and an optional shield/drain connection. This terminal-block design is purpose-built for industrial cabinets where vibration, temperature cycling, and maintenance access demand robust, tool-serviceable connections rather than consumer-grade RJ45 plugs. The RS485 interface supports baud rates up to 115.2 kbps and cable lengths up to 1000 meters, enabling the S7-1200 to communicate with distributed sensors, variable-frequency drives, motor management relays, weigh-scale terminals, and legacy RTUs over long trunk lines without signal repeaters.
