Transmit Four 4~20mA Analog Signals and 16 Digital Inputs Bi-Directionally Over Fiber with High Speed and Accuracy
This Fiber Optic Media converter transmits 4 channels of 4-20mA analog signals and 16 bi-directional contact closure signals over fiber cable. Premium features include 60,000 samples a second, 16 bit signal resolution, and less than 0.1% source signal variance.
Compatible with most PLC’s, Sensors (2, 3, or 4 wire), and other types of equipment where precise current or voltage measurements must be taken and transmitted over fiber. The high density contact closure feature allows for bidirectional alarm transportation.
This compact and rugged system provides convenient and easy to read LEDs, supports both single-mode and multimode fiber applications, and includes an alarm on either side for monitoring system power and fiber health.
Designed to operate over an extreme temperature range, providing reliability in harsh environments, each device is DIN rail and wall mountable. Designed and Made in the USA and covered by our Limited Lifetime Warranty.
