07KT94 Dc input interface circuit

07KT94 is a DC input interface circuit with a filter circuit and a photoelectric coupling circuit. The filter circuit can

eliminate the jitter of the input contacts, and the photoelectric coupling circuit can prevent the strong current interference

in the field from entering the PLC. Due to the optical signal coupling between the input electrical signal and the PLC

internal circuit, the two are electrically completely isolated, so that the input interface has anti-interference ability.
In addition, the input interface circuit of this model also has the following characteristics:
The field input signal is converted into 5V TTL through photoelectric coupling

and sent to the input data register, and then transmitted to the CPU through the data bus.

The main steps of the design and debugging of programmable controller application system include in-depth

understanding and analysis of the process conditions and control requirements of the controlled object.
Communicates with any drive, SCADA, and serial or Ethernet devices, and with the G315 integrated data

logger, records information in an “IT-Ready” CSV file on a CompactFlash card for further analysis or troubleshooting.
