PROFIBUS to Daisy Chain Fiber Converter, PROFIBUS to Fiber Converter


These products are PROFIBUS to fiber optic converters which secure PROFIBUS data transmission via fiber optical cabling for extending distance and isolating EMC/noise to reduce mutual interference between PROFIBUS devices. These products are protocol transparent, can be applied to the PROFIBUS, and also can be applied to other networks using RS485 interfaces (See Figure 1).

These converters are capable of selecting interface modes for connection to RS-485 2-wire half duplex or 4-wire full duplex. Additionally, the terminal block offers an alarm relay contact and two redundant DC power inputs. IFC Series converters are also available in two operating temperature ranges, a standard -10° to 60°C commercial temperature range and an extended -40° to 75°C range. With all these specifically designed features, the series is reliable and an ideal solution for keeping your industrial automation applications running smoothly and continuously even in harsh environments.
