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 Q172DRCPU MELSAP-L Manual Q172DRCPU Programming Manual
Q172DRCPU
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 Q172DRCPU MELSAP-L Manual Q172DRCPU Programming 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 Q172DRCPU MELSAP-L Manual Q172DRCPU Programming Manual. Input: 4 channels.
Platinum resistance (Pt100; JPt100).
No heater disconnection detection function.
Sampling period: 0.5s/4 channel.
18 point terminal station.
Peak current suppression.
Can prevent the simultaneous opening of the output to control the peak current, which is helpful for saving energy and reducing the operation cost.
Heating function at the same time.
The multiple loop can reach the set value at the same time to carry out the uniform temperature control,
Helps to prevent no-load and effective energy saving and reduce operating costs.
Automatic adjustment function.
The PID constant can be adjusted automatically in the control process.
Automatic adjustment of cost (time, material and electrical energy) can be reduced.
Can be flexible in various settings, to achieve the best temperature control of the temperature control module.
Equipment for high temperature control stability of extrusion molding machine,
The temperature regulating module has the function of preventing overheating and preventing over cooling Q172DRCPU MELSAP-L Manual Q172DRCPU Programming Manual.
According to the control object device, select the standard control (heating or cooling) or the heating and cooling contrrol (heating and cooling) mode Q172DRCPU MELSAP-L Manual Q172DRCPU Programming Manual.
In addition, the mixed control mode (combined with the standard control and heating - cooling control) can be selected.
