EtherCAT Junction Slave

Powering the Digital Transformation with EtherCAT

PLANET IECJ-400 is an industrial EtherCAT junction slave equipped with the EtherCAT protocol for today’s distributed industrial applications. The IECJ-400 4-port EtherCAT junction can be used in an EtherCAT Terminal segment at any desired position between the EtherCAT Terminals and enables the configuration of the EtherCAT star topology. A modular EtherCAT star hub can be realized by using several IECJ-400 units in a station. Its compact size and DIN-rail mounting make installation in a cabinet easy. Pluggable terminal blocks and LED indicator help users to maintain and set up their system.

IECJ-400 Features

Flexible Installation

The IECJ-400 is an ideal EtherCAT junction solution which provides quick installation, real-time connection status monitoring, wide-ranging power input and wide operating temperature to improve work efficiency, making them suitable for the harsh environment. Besides, both of them come with four 100BASE-TX RJ45 ports. Through the EtherCAT technology, up to 65,535 devices can be supported without the limitation of the type of topology — line, bus, tree, star or any arrangement — being used.


An EtherCAT slave is an electronic device that carries out cyclical sequences of calculations and/or data copying tasks at a certain interval (cycle). The EtherCAT slave working cycle (e.g. in the range of a few µs up to several ms) can be derived from different sources. EtherCAT node can measure time difference between leaving and returning frame. With distributed clocks, EtherCAT can realize a precise synchronization time of <1us between each slave module.

Convenient and Reliable Power System

The IECJ-400 is equipped with one 4-pin DC power input connector with screws for power supply installation. With power magnetic protection design, it can avoid the device burnout due to wrong wiring. In addition, it also possesses an integrated power supply source with wide-ranging voltages (9 to 48V DC) for worldwide high availability applications.

IECJ-400 Power System

Environmentally Hardened Design

With the IP30 metal industrial case, the IECJ-400 provides a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curb-side traffic control cabinets without air conditioning. It features a ventilated construction in which a cooling fan is not necessary, thereby making its operation noiseless. Being able to operate under the temperature range from -40 to 75 degrees C, the IECJ-400 can be placed in almost any difficult environment.

Dual Power Input for High Availability Network System

The IECJ-400 features a strong dual power input system with wide-ranging voltages (9V~48V DC) incorporated into customer’s automation network to enhance system reliability and uptime. In the example below, when power supply 1 fails to work, the hardware failover function will be activated automatically to keep powering the IECJ-400 via power supply 2 alternatively without any loss of operation.

IECJ-400 Dual Power

Flexible and Easy Installation with Limited Space

The compact-sized IECJ-400 is specially designed to be installed in a narrow environment, such as wall enclosure. It can be installed by fixed wall mounting or DIN rail, thereby making its usability more flexible and easier in any space-limited location.
