Product description

The Siemens 6ES7288-1ST20-0AA0 is a SIMATIC S7-200 SMART CPU ST20, a standard CPU designed for discrete control and small-scale automation tasks. It features 12 digital inputs and 8 digital outputs, all operating on 24V DC. The CPU has a program/data memory of 20 KB and operates within a supply voltage range of DC 20.4V to 28.8V, with a maximum input current of 720 mA at 24V DC. The transistor outputs offer high-speed switching and durability.

This micro PLC is ideal for very simple machine control, basic conveyor systems, small lighting controls, and simple pump or fan control applications. Its compact design makes it suitable for space-constrained environments. The CPU includes an integrated Ethernet/PROFINET port and an RS485 port for communication, supporting protocols like Modbus RTU.
