The CJ-AF series product is a multi-channel 4-20mA current analog optical fiber conversion device. Adopting ARM chip scheme, stable, reliable, and low power consumption. Simultaneously supporting transparent transmission of 1-4 channel current analog signals on optical fibers, without changing the user's communication protocol, it solves the problems of electromagnetic interference, ground loop interference, and lightning damage, greatly improving the reliability, stability, and confidentiality of control signals, and also solving the problem of close transmission distance in traditional methods. IP30 protection level, reinforced casing, 35mm guide rail installation, industrial standard DC24V power supply, with power polarity reverse protection function.
