Industrial Din Rail 4 Channel Analog + Dry Contact + Serial port Hybrid Optical Modem (with fiber break retention function)FC2P-042918

This series of devices utilizes large-scale FPGA design and proprietary technology to simultaneously support 1-4 channels of analog signals (current/voltage) or up to 4 dry contact signals, or up to 2 RS232/422/485 serial ports for transmission over fiber optic cables.

The device features dual power supply, a high-performance FPGA programmable device, no MCU processing, and high-speed conversion with a sampling frequency up to 20kHz and a 12-bit AD conversion chip.

This solves the problems of electromagnetic interference, ground loop interference, and lightning damage, significantly improving the reliability, safety, and confidentiality of control signals, while also overcoming the limitations of cable transmission distance.
