Transmit four 4~20mA Analog Signals over Fiber with High Speed and Accuracy
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 0.1% 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 and made in the USA, and covered by our Lifetime Warranty.
