RS485 FIBRE OPTIC CONVERTERS
The MOD-MUX RS485(RS422) / Fibre
Optic converter module is used to convert RS485 data communications signals for
transmission over fibre optic cables. The converters can be used to extend the
limited distance capabilities of RS485 devices for up to two kilometres. The RS485 Fibre Optic converter is
ideal for extending RS485 signals through areas of high electrical noise due to
the EMI immunity of fibre. Standard features of the
converter are : · Multiple Fibre Sizes. Three
fibre sizes are supported as standard on the converter module. · Industry Standard Fibre connectors. The
converter can be ordered for use with either the industry standard SMA or ST™
style connectors. · DIN Rail Mount.
The converter module plugs directly into a 11PIN industry standard relay
base which may be DIN rail mounted or flush mounted.
