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.
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 Program Fundamentals Manual Q20UDEHCPU User's Manual Q20UDEHCPU
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.
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 Program Fundamentals Manual Q20UDEHCPU User's Manual.
All the components in the security PLC adopt the redundancy structure,
Two processor processing for cross detection,
The processing 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 Program Fundamentals Manual Q20UDEHCPU User's Manual. MODBUS/TCP Master slave station.
10BASE-T/100BASE-TX.
MODBUS interface module capable of connecting MODBUS compatible device such as temperature regulator, measuring device and so on.
Support MODBUS communication function, and can be compatible with the third party MODBUS to communicate from various station equipment.
Support MODBUS communication functions from the station, can communicate with the third party programmable controller MODBUS master device.
Through the linkage function, the master can be coonnected to the CH1 side (RS-232),
And through the QJ71MB91 and connected to the CH2 side (RS-422/485) of a number of stations for communication Q20UDEHCPU Function Explanation.
The RS-232 interface (1 credit on the 1 pass) MODBUS master device withh multiple MODBUS communication from the station equipment Q20UDEHCPU Function Explanation. (only QJ71MB91)
Master / slave station functions can be used simultaneously. (only QJ71MT91)
