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
