S7-200 SMART, CPU ST20, STANDARD CPU, DC/DC/DC, 12DI/8DO
Onboard I/O: 12 DI 24 V DC; 8 DO 24 V DC; power supply: DC 20.4-28.8V DC; program/data memory: 20 KB; SIMATIC S7-200 SMART, CPU ST20, standard CPU, DC/DC/DC
A- Technical Parameter:
6ES7288-1ST20-0AA0 is a standard CPU module that uses a DC/DC/DC power architecture (DC power supply/DC input/transistor output). It is an improved version of the original S7-200 PLC, and, in terms of core control capabilities, it integrates high-speed computing functions, supporting high-speed counters (HSC) and pulse outputs with a maximum frequency of up to 100 kHz, which makes it appropriate for precise motion control scenarios like stepper motors and servo drives.
| Supply Voltage | DC 20.4–28.8 V (Wide voltage range design, adaptable to industrial voltage fluctuations) |
| Digital Inputs (DI) | 12 points, 24V DC input (Supports sinking/sourcing wiring) |
| Digital Outputs (DO) | 8 points, 24V DC transistor output (Maximum current per channel: 0.5A) |
| Output Type | Transistor output (Non-relay type, suitable for high-frequency switching scenarios) |
B- Communication:
It also has strong communication capabilities, including a built-in Ethernet interface that supports TCP/IP communication, allowing direct connection to touch screens, host computers, or other PLCs. Finally, it comes standard with an RS485 interface that is compatible with protocols like Modbus-RTU, USS, and PPI.
| Program Memory | 20 KB (for storing user programs) |
| Data Memory | 12 KB (for variable storage) |
| Processing Speed | Bit operations: 150 ns; Floating-point operations: 3.6 μs |
| High-Speed Counter (HSC) | Supports 6 channels (4 of which can be independently configured) |
| Pulse Output | 2 channels, maximum frequency of 100 kHz |
