Output points: 4 points (select the source type + drain type), 2 points (select the source type + source).
Isolation mode: photoelectric coupling.
Rated input voltage: DC24V QD75D4  PDF.
Security PLC (secure programmable system) refers to the self or external components or the implementation of the failure of the agency,
Can still respond to and promptly cut off the output of the programmable system QD75D4 
Different from ordinary PLC, security PLC not only can provide the function of ordinary PLC,
Safe control function can be realized,
Meet the requirements of the ISO 13849-1 EN and IEC 61508 control system safety related component standards QD75D4  PDF.
PLC security market mainstream has oilz (Pilz) PSS 3000, PSS 4000,
PSS 4000 in addition to the security process can also be processed outside the standard control procedures.
All the components in the security PLC adopt the redundancy structure,
Two processor processing for cross detection,
The processsing results of each processor are stored in their respective memory,
Output is only when the processing result is in full agreement,
If any inconsistency occurs during the process, the system is immediately shut down QD75D4  PDF QD75D4  Manual . "The most common station 11 units connected network: 121 MITSUBISHI User's Manual.
