Introduction
The
STF-502C series
is a dual fiber converter for serial
transmission. The fibers may be cascaded to form a
daisy chain, or looped to form a ring. Ring topology
provides added protection in case of a single fiber link
breakdown.
Features
Extends serial transmissions to 2km, 30km or 60km
Supports fiber daisy chain or ring connections
Redundant dual power inputs (12, 24, 48VDC)
Supports dual fiber link redundancy
Supports RS-422, RS-485(2/4 wire), RS-232
transmission to dual fiber connections.
Enhanced serial baud rate up to 1024kpbs
2.5KV isolation for serial signals
Supports relay output for power or link failure
warning
Hardened housing with IP30 protection
Fan-less and DIN-Rail design for harsh industrial
environments
Selectable terminator and adjustable pull high/low
resistor for RS-422/485 transmission
