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 Q172HCPU Special Instructions Manual Q172HCPU Strctured Programming Manual Q172HCPU
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 Q172HCPU Special Instructions Manual Q172HCPU Strctured 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 Q172HCPU Special Instructions Manual Q172HCPU Strctured Programming Manual. Program capacity: 124 K step.
Input / output points: 4096 points.
Number of input and output elements: 8192.
Processing speed: 0.034 s.
Program memory capacity: 496 KB.
Support USB and RS232.
CPU module expansion standard RAM (max 8MB).
Can be used with the SD memory card at the same time.
Continuous access file register.
Ultra high speed processing, production time is shortened, better performance.
As applications become larger and more complex, it is necessary to shorten the system operation cycle time.
The operation period can be shortened by the super high basic operation speed 1.9ns.
In addition to achieve in the past with the control of single-chip high-speed control,
The system performance can be improved by reducing the total scan time,
To prevent any possible performance bias.Input: 2 channels.
Input: thermocouple / micro voltage / voltage / current.
Conversion speed (input):25ms/2 channel.
Sampling period: 25ms/2 channel.
Output: DC4~20mA.
Conversion speed (output):25ms/2 channel.
18 point terminal station.
With 5 kinds of PID control mode.
Loop control module suitable for fast response object control, such as temperature control, flow control, etc..
The loop control module has a PID control format and a sampling period of 25ms that is proportional to the speed,
Support high precision, high resolution Thermocouple Input, micro voltage input, voltage input, current input and current output.
The most suitable for high speed lift and temperature control and pressure control, flow control and other requirements of the application of high speed response.
Can be connected with JIS, IEC, NBS, ASTM standard thermocouple.
Through the small voltage, voltage, current input sensor, can be measured in a variety of input range of analog.
Provides the pprogram control function, can according to the specific requirements of the time automatically change the target value (SV) and PID constant [proportional band (P), integratiion time (I), differential time (D)],
And cascade control function, allowing channel 1 as the main station, channel 2 for the control from the station Q172HCPU Special Instructions Manual Q172HCPU Strctured Programming Manual Q172HCPU Special Instructions Manual Q172HCPU Strctured Programming Manual.
