CFP\/1S is a RS422 synthetic fiber mains converter that converts RS422<\/a> electrical serial bus standard to plastic optical fiber with a screw-type connector. It can be used to extend the transmission distance of a serial communication or to isolate network branches. It can be mounted on a control panel with a 35 mm DIN rail and it’s very compact, only 2 DIN modules.<\/p>\n

CFP\/1S RS422 synthetic fiber mains converter is powered by 230 V mains voltage; it is fully Plug & Play and requires no drivers or DIP switches. The RS422 serial interface operates in full-duplex mode and automatically detects transmission speeds up to 250 kbps, making it easy to install in any new or existing system.<\/p>\n

 <\/p>\n

Use cases<\/h4>\n

A RS422 synthetic fiber mains converter is typically used to integrate multi-mode optical fiber links into an RS422 serial bus network. There are also environments where electrical equipment is prohibited, such as swimming pools, saunas, and buildings at risk of fire, where fiber optics therefore become necessary.<\/p>\n

The transmission speed is certainly more limited than glass fiber, but it is still more than sufficient for the few Mbps required in industrial applications. In building automation, controlling modules on an RS422 bus requires a few hundred kbps, and synthetic optical fiber is definitely recommended for isolating different zones of a system.<\/p>\n

 <\/p>\n

Advantages<\/h4>\n

In a system, it is good practice to install a RS422 synthetic fiber mains converter at the beginning of a multi-mode fiber run, and a repeater such as the TSS\/1F<\/a> on each floor. This helps reduce issues related to ground potential differences or possible power surges. Optical fiber is a perfect electrical insulator and therefore protects the RS422 bus from the propagation of lightning strikes or other atmospheric discharges.<\/p>\n

Fiber optics isolate various branches of a network, such as the floors of a hotel or sections of a photovoltaic system, from electromagnetic interference (EMI) and power surges. Electromagnetic interference is common in these environments, so it is good practice to install two or more optical-to-electrical converters to ensure signal integrity.<\/p>\n

Furthermore, a RS422 synthetic optical fiber converter allows for the regeneration of the electrical signal, thereby improving communication quality.<\/p>\n

 <\/p>\n

Protocol<\/h4>\n

CFP\/1S RS422 synthetic fiber mains converter is completely independent of the protocol used. This means that the converter is transparent to the communication and can be used with protocols such as Modbus, BACnet, or any proprietary protocol.<\/p>\n

This is possible because the converter operates at the logical levels, rather than at the protocol level itself. Therefore, this RS422 synthetic fiber mains converter can also be used in complex networks where multiple protocols are present simultaneously on the same RS422 bus.<\/p>\n

 <\/p>\n

Versatility<\/h4>\n

The RS422 synthetic fiber mains converter is available with other combinations of serial and fiber optic standards, or with a low voltage power supply. The CFP\/1V<\/a> and CFP\/1Q<\/a> converters, for example, accept glass fiber with a bayonet connector or synthetic fiber with a Versatile Link connector, respectively. The CRP\/1S<\/a> and CMP\/1S<\/a>, on the other hand, are suitable for various serial standards, namely RS232 and RS485.<\/p>\n

The CFM\/1S<\/a>\u00a0 RS422 synthetic optical fiber converter is functionally identical to CFP\/1S but accepts a wide range of low-voltage AC and DC power supplies. All combinations of serial standards, optical fiber types, and power supply options are available in the catalog; however, special requests (such as higher data rates) can be made via the contact form.<\/p>\n","protected":false},"excerpt":{"rendered":"

CFP\/1S is a RS422 synthetic fiber mains converter that converts the standard electrical RS422 bus signal to plastic optical fiber using a screw-type connector.<\/p>\n

 <\/p>\n

It isolates the various branches of a system from electromagnetic interference, electrical surges, or even lightning strikes.<\/p>\n

 <\/p>\n

The screw-type connector greatly simplifies installation; no specialized tools are required for fiber termination.<\/p>\n

 <\/p>\n

It is completely protocol-transparent, so it can be used with Modbus or any proprietary protocol operating on an RS422 bus.<\/p>\n

 <\/p>\n

It operates at 230 V mains voltage, is fully Plug & Play, and requires no drivers or DIP switches. The RS422 serial interface operates in full-duplex mode and automatically detects baud rates up to 250 kbps, so it can be easily installed in any new or existing system.<\/p>\n","protected":false},"featured_media":2609,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[282],"product_cat":[257,265,261],"product_tag":[273,274,280,278,281],"class_list":["post-3115","product","type-product","status-publish","has-post-thumbnail","product_brand-cle-automazioni","product_cat-isolation","product_cat-optical-fiber","product_cat-rs422-en","product_tag-converter","product_tag-din-rail","product_tag-optical-fiber","product_tag-rs422","product_tag-synthetic-fiber","first","instock","shipping-taxable","purchasable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/cle-automazioni.com\/en\/wp-json\/wp\/v2\/product\/3115","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cle-automazioni.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/cle-automazioni.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/cle-automazioni.com\/en\/wp-json\/wp\/v2\/comments?post=3115"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cle-automazioni.com\/en\/wp-json\/wp\/v2\/media\/2609"}],"wp:attachment":[{"href":"https:\/\/cle-automazioni.com\/en\/wp-json\/wp\/v2\/media?parent=3115"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/cle-automazioni.com\/en\/wp-json\/wp\/v2\/product_brand?post=3115"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/cle-automazioni.com\/en\/wp-json\/wp\/v2\/product_cat?post=3115"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/cle-automazioni.com\/en\/wp-json\/wp\/v2\/product_tag?post=3115"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
