Maximize performance and productivity in your manufacturing processes with Siemens 6ES7 331 7HF01 0AB0. The family line of connectors that the product belongs to, or can be connected to, is S7/300. This user-friendly Siemens Analog Output Module device offers good flexibility in process creation and implementation delivering good performance at any time.

The communications port allows you to connect the CPU to a programming device or to other devices. Status lights provide visual information about the CPU mode (RUN or STOP), the current state of the local I/O, and whether a system fault has been detected. Some CPUs provide a real-time clock as a built-in feature, while other CPUs require the real-time clock cartridge. A plug-in serial EEPROM cartridge provides a means to store CPU programs and transfer programs from one CPU to another. A plug-in battery cartridge provides extended retention of data memory in RAM
