Overview

The Analog Signal DIN Fiber Link system transmits an analog signal, 4~20mA or 0~10VDC, over one optical fiber. This system is designed to provide highly accurate signal transmission at a high sample rate.

Compatible with most PLC's, Sensors (2, 3, or 4 wire), and other types of equipment where a precise current or voltage measurement needs to be taken and transmitted over fiber. The system comprises of a transmitter (TX) and a receiver (RX), each enclosed in a compact DIN and wall mountable housing.

This compact and rugged system provides convenient and easy to read LEDs, supports both singlemode and multimode fiber applications, and includes an alarm on the receiver enabling system health monitoring. RLH Fiber Link systems are designed to operate over an extreme temperature range, providing reliability in harsh environments. It is made in USA and covered by our Limited Lifetime Warranty.
