4 Channel 4~20mA Fiber Converter
with SFP
FBX-420-INPUT-1 / FBX-420-OUTPUT-1
Transmit four 4~20mA Analog Signals over Fiber
with High Speed and Accuracy
Introduction
The RLH 4~20mA Fiber Optic Converter transmits 4 Analog
signals over fiber cable and offers high performance with 500k
samples per second, 16 bit signal resolution, and less than
0.2% source signal variance.
It is compatible with most PLC's, Sensors (2, 3, or 4 wire), and
other types of equipment where a precise current
measurement must be taken and transmitted over fiber. The
system comprises of a transmitter (Analog Input) and a receiver
(Analog Output).
This compact and rugged system provides convenient and easy to
read LEDs, supports both singlemode and multimode fiber
applications, and includes an alarm contact for monitoring system
power and fiber health.
This system is engineered to operate over an extreme
temperature range, providing reliability in harsh environments.
It is designed in the USA, and covered by our Lifetime
Warranty.
