The analog input module converts analog signals from the process to digital signals for internal processing by the fail-safe SIMATIC S7 CPUs.
The safety functions required for fail-safe operation are integrated in the module.
The following functions are available:
- Resolution 15 bits + sign.
- Measuring ranges:
- 0 to 20 mA or
- 4 to 20 mA or
- 4 to 20 mA (HART)
- Interrupt capability;
the module sends diagnostic interrupts to the CPU of the controller. - Diagnostics;
the module sends extensive diagnostic information to the CPU.
