It is a device based on planar optical waveguide technology solutions, including: splitter, star coupler, adjustable optical attenuator, optical switch, optical comb and array waveguide grating.
1746-IV32
The advantages of 1746-IV32 are as follows:
The relay control logic uses hard-wired logic, the relay mechanical contacts in series or parallel, and the time relay are combined into
a control logic, which has many and complex connections, large volume, large power consumption, high failure rate, poor flexibility and
scalability. The PLC uses memory logic, and its control logic is stored in memory by program, which has good flexibility and expansibility.
Working mode – Each relay in the relay control line is in a controlled state at the same time, which is a parallel working mode. In the
control logic of PLC, the internal devices are in the process of cyclic scanning, and the results of various logic and numerical output are
calculated in accordance with the order in the program, so it belongs to the serial working mode.
Reliability and maintainability – The relay control logic uses a large number of mechanical contacts and many connections, and the reliability
and maintainability are poor. The PLC uses microelectronics technology, a large number of switching actions by contactless semiconductor
circuits to complete, PLC is also equipped with self-test and supervision functions, reliability and maintainability is good.
Control speed – The relay control logic relies on the mechanical action of the contact to achieve control, the working frequency
is low, and the mechanical contact will also jitter. The PLC is controlled by the semiconductor circuit controlled by the program instruction,
which belongs to contactless control, the speed is extremely fast, and there will be no jitter.
Timing control – Relay control logic uses time relays for time control. The timing accuracy of time relay is not high, the timing range is
narrow, and it is easy to be affected by the change of ambient humidity and temperature, and it is difficult to adjust the time. PLC uses
semiconductor integrated circuit as timer time base pulse generated by crystal oscillator, the accuracy is quite high, and the timing time is
not affected by the environment, the timing range is wide, and the adjustment time is convenient.
