The TTL digital signal converters belong to the Cj-df series of products. This series includes a type of digital signal, multi-channel analog signal and serial ports RS232/485/422 fiber conversion multiplexing equipment.
The latest ARM chip is adopted which features reliable low power and stability. It supports 1 to 4 channels of the digital TTL signal/contact closure signal, 1 to 4 channel analog (voltage/current), 1 to 2 channel RS232/485 or a channel RS422 signal in the fiber or multiplexing transmission.
No change of the user communication protocol is required and the issue of electromagnetic interference and the ground ring interference which thunder destroys is solved. This considerably enhances the signal reliability and safety confidentiality whilst solving the issue of the traditional mode of short distance transmission.
