Mitsubishi's QJ72LP2525C, an integral part of the Melsec-Q series, is optimized for network communication. This NET/H remote input/output controller employs a token ring approach within its optical loop system, ensuring precise and reliable data transfers. The encoding method used is Non Return to Zero Inverted (NRZI), coupled with frame synchronization to maintain data integrity throughout the communication process.
Operating at a communication speed of either 10 or 25 megabits per second, this controller can handle significant data loads. It weighs in at 0.33 pounds (0.15 kilograms) and features compact dimensions, measuring 3.54 inches in height, 1.08 inches in width, and 3.54 inches in depth (90 mm x 27.4 mm x 90 mm).
Designed for high flexibility, the QJ72LP2525C can manage up to 239 separate networks with a duplex loop structure, allowing connections to 65 stations within each network. The controller also exhibits a low interior current consumption of 0.89 Amperes when powered by 5 Volts DC. Additionally, it supports an impressive maximum cable distance of 30 kilometers, making it suitable for extensive installations. Furthermore, the conformal coating offers protection against environmental factors, enhancing durability in demanding settings.
