Transmit four 4~20mA Analog Signals over Fiber with High Speed and Accuracy
This Fiber Optic Media converter transmits 4 Analog signals over fiber cable. Offers high end specifications: 78,000 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 a precise current or voltage measurement must be taken and transmitted over fiber. The system comprises of a transmitter (Analog Input) and a receiver (Analog Output), each device is enclosed in a compact DIN and wall mountable housing.
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 monitoring system power and fiber health. Designed to operate over an extreme temperature range, providing reliability in harsh environments. Designed and Made in the USA and covered by our Limited Lifetime Warranty.
