- 1~2 channels rs-232 serial optical fiber converter, solve the contradiction between communication distance and communication rate, and solve the problem of electromagnetic interference, earth ring interference and lightning damage.1~2 channels serial optical fiber converter, RS232 fixed rate, single multi-mode optical fiber 0~20km, longer distance, optical interface type ST/SC/FC is optional. Without changing the user's communication protocol, it solves the problems of electromagnetic interference, earth ring interference and lightning damage, greatly improves the reliability, security and confidentiality of control signals, and at the same time, solves the problem of short transmission distance in the traditional way. IP30 protection grade, reinforced housing, 35mmDIN rail installation, industrial standard DC 24V power supply, with power polarity reverse connection protection function.
