The Siemens 6ES7231-5QA30-0XB0 SB 1231 is an Analogue Input Signal Board that converts analogue signals from Thermocouple inputs and processes them into digital signals for internal processing by the SIMATIC S7-1200. With analogue signal boards, users can optimally adapt their controllers even to more complex tasks.
Signal boards are plugged directly into the SIMATIC S7-1200-CPU and are thus connected electrically and mechanically with the CPU.
