More Description

Model FOSCTDRI-PH-SC is a premium heavy industrial serial-to-fiber optic converter. Designed for rugged industrial environments, it has been put through some of the most exacting compliance testing in the industry. Meeting IEC 61850-3 and IEEE 1613 requirements, it is suitable for installation in electrical substations. These specifications are more stringent than NEMA TS1/TS2 requirements for transportation applications. Powerful isolation protects equipment and data from damaging ground loops and surges. Additional isolation on the power supply circuits adds a third level of protection. An external 10-48 VDC power source is required (not included, sold separately). Packaged in a rugged IP30 metal case, this converter converts serial signals to single-mode fiber optic. Bit-wise enabled circuitry automatically detects the data rate without setting a DIP switch. In addition to direct point-to-point connectivity, operation in multi-drop mode is possible. This enables serial devices to communicate with up to 31 others in a fiber ring. Supporting mixed standards, you can replace other converters and add the EMI / RFI protection inherent to fiber optic communications. Note: These converters use a proprietary modulated fiber optic signal. Two units are required to extend the data via the fiber optic connection. Any FOSTCDRi-PH-x converter can (only-) connect to another FOSTCDRi-PH-x converter model at the other end of the fiber optic cable.
