According to the different communication interfaces and whether the fail-safe function is integrated, the CU240E-2 can be divided into six models:

CU240E-2 (RS485 interface);

CU240E-2F (RS485 interface, integrated fail-safe function);

CU240E-2DP (Probus-DP interface);

CU240E-2DP-F (Probus-DP interface, integrated fail-safe function);

CU240E-2PN (ProfiNet interface);

CU240E-2PN-F (ProfiNet interface, integrated fail-safe function);

The definitions of the input/output terminals of different types of controllers are basically the same. The control unit with F function (fail-safe) has a fail-safe digital input (F-DI) channel.

The following table lists the definitions of common terminals for CU240E2 (RS485):

For the control unit integrated with the fail-safe digital input (FDI), the original 6-channel digital input, two by two, is used as a fail-safe FDI (for example: DI4 and DI5 form FDI0). The definition of F-DI is as follows:

Encoder|Transmitter|Soft starter|Power supply|VFD|Light curtain|Servo products|Human-machine interface|Solenoid valve|Cylinder|Actuator|Flow meter|Transformer|Thyristor|Sensor|Deceleration drive gearbox reducer|Linear guide|Circuit breaker|Refrigeration compressorAll industrial products of okplazas are purchased from the original factory or formal channels of agents to ensure the original authenticity, which perfectly solves the problem of industrial product sample procurement and small-batch procurement for the majority of engineers and purchasing personnel.
