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 Q172CPU Special Instructions
Q172CPU
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 Q172CPU Special Instructions.
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 Q172CPU Special Instructions. "5 slots.
The main substrate needs to be equipped with CPU and power supply.
Support for high speed communication between multi CPU.
Requires 1 power modules.
Used to install Q series modules.
A variety of modules with excellent performance,
Meet the needs of various control from analog to location.
Q series module products include a variety of types of I/O, analog and positioning function module.
Can fully meet the switch, sensor, such as the input and output, temperature, weight, flow and motor, drive control,
As well as the requirements of high-precision control of the positioning of the industry, the control needs of various fields.
Can also be used in combination with the CPU module to achieve appropriate control.Output: 2 channels.
Input (resolution): 0~12000; -12000~12000; 0~12000; -16000~16000.
Output DC0~20mA; DC-12~12V.
Conversion speed: 10ms/1 channel.
18 point terminal station.
Isolation between channels.
The possibility of expanding control with intelligent function.
At the same time, the channel isolation analog module realizes high isolation voltage,
Further improve the accuracy of the benchmark.
Provide support for process control using a general purpose programmable controller.
Flow meter, pressure meter, other sensors can be directly connected to analog input,
Control valve can also be directly connected to analog output.
Hardware and installation costs have been greatly reducced due to the need for an external isolation amplifier Q172CPU Strctured Programming Manual.
High insulation strength.
Can isolate electrical interference, such as current and noise, etc..
Standard analog input module.
Isolated analog input module. Q172CPU Strctured Programming Manual.
No external isolation amplifier required.
Without the use of inter channel isolation analog modules.
Using the inter channel isolation analog module.
