The PLANET IECJ-300 is a compact, industrial-grade EtherCAT junction slave designed for distributed automation applications. Featuring three 100BASE-TX RJ45 ports, it supports flexible EtherCAT topologies such as line, bus, tree, and star – with up to 65,535 devices. Its rugged IP30-rated metal casing, wide operating temperature range (-40 to 75°C), and dual 9–48V DC power input with redundancy make it ideal for harsh environments.

With support for EtherCAT Distributed Clocks, the IECJ-300 enables sub-microsecond (<1 μs) synchronization between modules. Its fanless design ensures silent operation and high reliability in space-restricted control cabinets or environments lacking active cooling.
