Description

The Moxa EJS-08 is a compact 8-port EtherCAT junction with 100BaseT(X) RJ45 ports, built to convert between star, line, tree and ring topologies in industrial automation networks. The standard temperature model operates from -10 to 60°C, and the metal IP30 housing suits DIN-rail installation inside control cabinets.

Dual 12/24/48 VDC power inputs (9.6 to 60 VDC operating) provide redundant power, with overload current and reverse polarity protection. The EJS-08 offers 8 FMMU and 8 Sync Manager channels, is EtherCAT Conformance Test certified by the ETG, and meets EN 61000-6-2 and EN 61000-6-4 industrial EMC standards. It also supports DIN-rail grounding and wall mounting with an optional kit.

FAQs

Q: Which network topologies does the EJS-08 support?
A: The EJS-08 supports star, line, tree and ring topologies, so it can convert between them and make EtherCAT network layouts more flexible.

Q: What power input does the EJS-08 require?
A: It accepts 12/24/48 VDC nominal, with an operating range of 9.6 to 60 VDC. Two power inputs allow redundant supply, and the unit includes overload current and reverse polarity protection.

Q: What is the operating temperature range of this model?
A: This standard temperature model operates from -10 to 60°C. Storage temperature is -40 to 85°C.

Q: How is the EJS-08 mounted?
A: It mounts on a DIN rail, and wall mounting is possible with an optional kit. The IP30 metal housing is intended for installation inside a control cabinet.

Q: Which port is the input port?
A: The port combination is 1 IN and 7 OUT. Port 1 is the input towards the EtherCAT master and the other seven ports connect downstream slave devices.

Q: What port speed and cable length does the EJS-08 support?
A: All eight RJ45 ports are 100BaseT(X) with auto MDI/MDI-X, supporting cable runs of up to 100 m.
