Contact Alarm Relay/Optical Converter FRM220-CCF Series
The connection alarm will be extended with optical fiber.
The FRM220-CCF is a relay contact converter that opens and closes contacts via a single-core optical fiber link. By inserting an SFP module into the optical fiber port, fiber communication is possible. Using a WDM SFP module also enables bidirectional communication. The FRM220-CCF has contact inputs and a 0.5 amp contact output. The contact closure module has two relay outputs and two relay inputs, with the relay outputs following the "relay input" on the remote side. If the remote "relay input" is short-circuited, the local relay output will close, and vice versa. The second relay output will close when a "carrier" is detected on the remote side. This indicates that the optical fiber is connected and that there is power and operation at the remote end.
