2 Channel 4 Wire Data
with E&M and I/O
DIN Fiber Link System
SYSTEM INSTALLATION INFORMATION
This industrial fiber optic media converter is designed to extend two
4 Wire Voice Frequency Signals over fiber optic cable. This system
also features bi-directional contact closure for remote relay or alarm
status transportation. By utilizing fiber cable you gain the advantage
of sending the signal long distances, up to 120km, as well as gain
noise immunity to RF and electromagnetic interference.
This system transports 2 channels of 4 Wire Data with E&M.
The 4 wire data supports constant transmission of voice frequency
ranging from 300Hz-3400Hz suitable for a wide range of radio
and SCADA applications. The devices can be ordered with
dual fiber or single fiber transceivers. This RLH Fiber Link
system is designed and made in the U.S.A. and covered by our
Limited Lifetime Warranty.
