Product Description
Product description
The HC-SERIAL-SFP is a SET of TWO industrial grade fiber media converters that extend asynchronous RS-232 and RS-485/RS-422 serial interfaces over one strand only of a fiber optic circuit, either SM or MM type. The set is capable of transporting both RS-232 and RS-485/422 interfaces simultaneously and independently of one another. Interfaces for connection to RS-232 (3 wire) and RS-485 (2 or 4 wire, half or full duplex)/RS-422 (4 wire, full duplex) and available separately on the 7 pin block connector on the front panel of the media converter. The HC-SERIAL-SFP Series secures asynchronous serial data transmissions over EMI resistant fiber at speeds up to 256kbps. HC-SERIAL-SFP media converter units have each two redundant DC power inputs. The media converter's industrial design is perfect for keeping your industrial automation applications running smoothly and continuously. The HC-SERIAL-SFP media converter set is available with an extended -40° to 75°C operating temperature range.
