Boost the capacity of your PLC I/O modules with this expansion unit from Siemens. It's designed for use with S7-300 series PLCs and performs high-speed counting functions for your controller. The device has a 32-bit counting range, so it has a high counter limit, making it useful for advanced process control. You can link it to both symmetrical and asymmetrical incremental encoders, making it a versatile choice for your automated systems. For electrical safety, the unit has potential separation across its input, output and backplane bus. This means there's no direct connection between them, reducing the risk of equipment damage. You'll find a module like this one useful in packaging and production facilities.

• Light weight of 250g for minimal strain on your equipment
• Three input channels for effective multi-signal transmission
• Integrated air vents for passive cooling without external ventilation devices
• 9mA input current for energy efficiency

This counter module comes equipped with a configuration CD to let you monitor and manage it from a computer.
