MO1918-0000-1112 | I/O module, 8-channel digital input, 24 V DC, 0.5 A, M12, TwinSAFE, TwinSAFE Logic

The MO1938-0000-1112 TwinSAFE component provides safe digital inputs and outputs (outputs with up to 0.5 A). The module also has eight fail-safe inputs for sensors with potential-free contacts for 24 V DC.

The MO1938 has safety parameters to specifically adapt the functionality to the respective safety requirements (e.g. testing of the individual channels).

The safety parameters are not stored directly on the component, but are transmitted to the module via a TwinSAFE Logic-capable component when the safety application is started. This simplifies service procedures, because in this case the component can simply be replaced. The safety-relevant parameters are transferred to the new component when the safety application is restarted.

A further highlight is the integration of the functionality of the EL6910 TwinSAFE Logic EtherCAT Terminal. The MO1938-0000-1112 module can also be used as a safety controller. With the help of the locally available inputs and outputs, a complete safety application can be realized directly on the component. The range of functions corresponds to that of the EL6910. The only difference is the limitation of the number of possible safe connections to 128. Apart from that, all the advantages of the new generation of safety controllers can be used (see EL6910 customizing, incremental download, analog value processing, etc.).

Special features:

• 8 safe inputs
• 8 safe outputs
• integrated TwinSAFE Logic (functionality similar to the EL6910)
• up to 128 safe connections
• complete safety loop can be realized directly on the component
• Standard outputs can be activated with integrated ANDing with a safe output signal.
