"*" indicates required fields
Product Overview
The Siemens 6ES7 288 1SR30 0AA1 is a central processing unit from the highly popular SIMATIC S7 200 SMART series. This compact controller is specifically engineered to balance high performance with cost effectiveness for small to medium scale automation tasks. It serves as the brain of the control system and is widely deployed in packaging machinery conveyor systems and general industrial equipment where reliable logic control is required.
Input and Output Configuration
This standard CPU module is equipped with a total of thirty onboard digital input and output points providing a substantial amount of local control capacity. The configuration consists of eighteen digital inputs and twelve digital outputs. A defining characteristic of the SR30 model is its relay type outputs. Unlike transistor outputs relay outputs offer the flexibility to switch both AC and DC loads and can handle higher currents which reduces the need for external interposing relays in many applications.
Communication Capabilities
Connectivity is a major strength of this device as it features an integrated Ethernet interface directly on the CPU unit. This standard Ethernet port facilitates high speed programming and communication with Human Machine Interfaces and other PLCs without the expense of additional communication modules. Furthermore the unit retains a traditional RS485 port which ensures compatibility with serial devices sensors and variable frequency drives using the Modbus RTU protocol.
Power and Usability
The controller is designed to operate on a standard AC power supply typically ranging from 85 to 264 volts AC which simplifies installation by eliminating the need for an external 24 volt DC power supply for the main unit. It also supports a commercial micro SD card slot which allows technicians to easily update the program firmware or restore factory settings without needing a computer connection. The system is programmed using the user friendly STEP 7 Micro WIN SMART software.
