Description
Siemens 6ES7288-1ST20-0AA1 is a SIMATIC S7-200 SMART CPU ST20 for compact automation equipment using a 24 V DC control supply. The DC/DC/DC controller integrates twelve 24 V DC digital inputs and eight 24 V DC transistor outputs, providing electronic switching for standard logic, high-speed pulses and motion-related functions documented by Siemens.
The CPU provides 20 KB of integrated program and data memory, web-server support and onboard Ethernet and RS485 communication. It is engineered with STEP 7 Micro/WIN SMART; supply quality, output current, polarity, load suppression, grounding, firmware, network configuration and installation conditions must follow the current Siemens S7-200 SMART System Manual.
