  • Transmits contact closure over a fibre optic link
  • Point-to-Point operation
  • Distances up to 120km
  • Relay output follows the “relay input” from the remote end
  • Relay contact for Carrier Detect, N.C. (Normally Closed)
  • SNMP & Web management option

Overview

The FRM220-CCF-SA contact closure fibre converter comes in two versions, one with 2 channels (CCF20-SA) and one with 4 channels (CCF40-SA) and provides transmission of contact closure over a single fiber optic link.  An SFP slot  provides for a wide variety of fibre options - single or multi-mode , as well as BiDirectional which allows transmission using only a single fiber. The FRM220-CCF has contact inputs and 0.5 amp contact output relays. The relay output follows the “relay input” from the remote end. When the remote “relay input” is shorted, the local relay output is closed and vice-versa.  Any  of the relay outputs can be configured to close when “carrier loss” is detected from the remote end.   Carrier Loss indicates that the optical fibre is disconnected or that the remote end has lost power and is not operating. This "carrier loss" relay can then be connected to an appropriate alarm circuit.

This unit is fully interoperable with the chassis mounted FRM22-CCF40/20 card versions.
