Compact PLC CPU • CR30 Class • AC/DC/Relay
A compact SIMATIC S7-200 SMART controller solution for machine-level automation, combining integrated digital I/O with a space-efficient CPU architecture.
The S7-200 SMART CR30 class is designed around compact machine automation, where a controller must combine CPU functionality and onboard digital I/O without requiring a large control cabinet footprint.
Its integrated I/O architecture makes it suitable for control tasks involving discrete sensors, switches, actuators, contactors and relay-controlled loads.
Compact sequencing and discrete automation tasks.
Sensor and actuator signal handling.
Useful when matching an existing CR30 control architecture.
A replacement CPU can help restore machine control after hardware failure.
Fast handling for automation replacement requirements.
Warranty support for supplied equipment.
Prepared for industrial replacement requirements.
