Fiber optic modem SFT-2
TRANSSMISON UP TO 4 DIGITAL INFORMATIONS OVER FIBER
Features
FEATURES
TWO REALY OUTPUTS NC AND NO FOR EACH AWAY INPUT USES 2 OPTICAL MULTI-MODE FIBERS (ST CONNECTORS) SUPPORTS DATA TRANSMISSION UP TO 3 KM LED STATUS AND OPERATION INDICATION
PRODUCT DESCRIPTION SFT-2 module from the SFT family of optical transceivers is intended for transmission of up to four input/output digital informations using multi-mode (MM) optical fiber as a transfer medium. Device has inbuilt HFBR optical transceivers that enable connection of MM fibers with ST ending connectors. SFT-2 needs 2 optical fibers and supports transmission lengths up to 3 km. Transmission channels are electrically isolated. Output relays gives two possibilities of outputs: NO – normally open, and NC- normally closed for each of four outputs. Power supply and serial communications are connected through serial blocks. The device is enclosed in an industrial non-flammable plastic housing that is adapted for a straightforward installation to a standard DIN rail. Its small size makes it a perfect solution when mounting into small stations is needed. On the front of the enclousre are transparently placed LED indications which provide a quick insight into the basic functions of the operating device, they are reporting a possible break on the optical communication link, the presence of portable power, presence and activiy of I/O informations. Power supply is adapted for alarm equipment. It has builtin protection against incorrect voltage connection.
