CFM/1Q is an industrial optical-electrical converter, RS422 to synthetic optical fiber with Versatile Link connector, powered by a low voltage supply. It can be used to increase the transmission distance of a serial communication, or to isolate different branches of a network. Thanks to its compact 1-module DIN rail housing, it can be easily mounted in an electrical panel. It accepts a wide range of AC and DC voltages, and it is completely Plug&Play, since it does not need any driver nor DIP switch. This RS422 serial converter is Full Duplex and it automatically detects the transmission data rate up to 40 kbps, so it can be easily installed in any new or existing network.
Optical-electrical converters are typically used to integrate a section of optical fiber in a RS422 low voltage network, in order to increase the transmission distance. They isolate the different branches of a network from electromagnetical interferences (EMI) and voltage surges, like the different floors of a hotel, or various branches of a solar power system. Electromagnetical interferences are fairly common in these environments, so it is good practice to integrate two or more optical-electrical converter to guarantee signal integrity. Furthermore, there are environments where electrical devices are strictly forbidden, such as pools, saunas, fire-risk buildings, so optical fiber is mandatory.
Optical-electrical converters are available with different combinations of serial standard and optical fiber, or powered by 230 V. CFM/1S and CFM/1V converters for example accept synthetic optical fiber with a screw connector, or glass optical fiber with Bayonet connector, respectively. CRM/1Q and CMM/1Q are suitable for different serial standards, that is RS232 and RS485. Industrial serial converter CFP/1Q is functionally identical to CFM/1Q, but it is powered by 230 V mains voltage. Every combination of serial standard, optical fiber, and power supply, is however available, while special requests (such as higher data rates) can be made via the contact form.
