The Siemens 6ES7288-1SR20-0AA1 is a CPU SR20 module for S7-200 SMART systems. It features 12 inputs, 8 relay outputs, and integrated PROFINET connectivity.
Siemens 6ES7288-1SR20-0AA1 as a central controller for compact automation solutions. This CPU module belongs to the SIMATIC S7-200 SMART family and features relay outputs. Specifically, the unit provides 12 digital inputs and 8 digital relay outputs for direct device control. Furthermore, each relay output supports a switching capacity of up to 2 A for various loads. The device operates efficiently on a wide-range AC power supply from 85 V to 264 V. Alternatively, users can power the module with a DC voltage between 77 V and 138 V. Processing occurs rapidly with a typical execution speed of 0.15 µs per basic logic instruction. Additionally, the integrated work memory offers 20 KB for both program code and data storage. Operators may also insert an optional microSD card to expand data logging capabilities. Connectivity options include one integrated RS485 port and one PROFINET Ethernet interface. Consequently, the CPU supports standard protocols like Modbus RTU and TCP/IP seamlessly. Facilities mount the compact unit on a standard 35 mm DIN rail for easy installation. Moreover, the built-in supercapacitor preserves data for several days during power outages. This robust design ensures reliable performance in diverse industrial environments without extra batteries.
