Compact CPU with integrated input and outputs
Models with PROFIBUS DP interface (DP) or point to point interface (PtP)

Operation requires a SIMATIC Micro Memory Card and front connector (Order no. 453-2589)

Process data and instructions quickly and clearly with this compact CPU (central processing unit) from Siemens. It has 24 digital and 4 analogue inputs, so it can receive physical measurements as well as inputs from computer programmes. It's practical for use in industrial automation, robotic machinery and the automotive industry thanks to 4 high-speed counters that process data at 60kHz per second. This small-scale unit measures just 120 (W) x 125 (L) x 130mm (D), so it's useful in areas where space is limited. It has an MPI (message passing interface), which allows it to communicate conveniently with other controllers and operator panels.

• Easily mounted on a DIN rail or wall for quick installation
• PWM (pulse width modulation) outputs enable the control of valves and actuators
• 192kB (kilobyte) working memory allows multiple applications to function simultaneously without delay
• Capable of simple motion control to manage the velocity, position and acceleration of loads

Yes. In order to function this CPU needs a SIMATIC micro memory card (467-642) and front connector (453-2589).

This CPU runs on a 24V DC circuit, so it adheres to automation industry standards.
