The fiber optic system IOL3000 transmits digital signals (e.g., contact closures, control-signals) and analog signals via fiber optics.

The fiber optic system is able to transmit up to 8 digital signals (12–24 VDC) and/or 4 analog signals (0–10 V or 0–20 mA, digitalized via A/D converter with a resolution of 10 Bit) within a point-to-point structure or line-structure.

The interconnection of an input/pass system (ED) allows the transmission of additional digital and analog data. You can choose if you want to have an electric disjunction (OR) of electrically and optically received data or if the electric data shall overwrite the optical data. In case of analog data the DIP switch must be used to decide whether the optical or the electrical signals shall be transmitted. The devices are available for line or ring structures as one fiber solutions.

LEDs and potential-free contacts of a fault detector relay are able to signal defective states.
