HIMA EL9010

Technical Specifications: Supply voltage is derived from E-Bus with no external power supply required. Electrical isolation reaches 500 VRMS between E-Bus and signal voltage. The unit weighs approximately 50 g, with an operating ambient temperature range of 0°C to +55°C and a storage temperature range of -25°C to +70°C. Permissible relative humidity ranges from 5% to 95% under non-condensing conditions. It conforms to EN 61000-6-2 and EN 61000-6-4 EMC standards, and meets EN 60068-2-6, EN 60068-2-27, EN 60068-2-29 vibration and shock resistance standards. Protection class is IP20, and installation position is variable.

Functional Features: It terminates E-Bus signals to maintain signal integrity in terminal chains, and requires no address configuration or software setup. Its compact form factor saves cabinet space, and integrated signal LEDs provide operation status indication.

Application Scenarios: It applies to industrial automation control systems, EtherCAT-based servo drive systems, production line I/O terminal assemblies, and process automation equipment.

Performance Parameters: Current load capacity of power contacts reaches up to 10 A. Stripping length for wiring ranges from 8 to 9 mm. Signal transmission speed matches standard EtherCAT E-Bus rates.

Material Composition: The housing is made of polycarbonate with high electrical insulation and chemical resistance. Conductive components adopt tin-plated copper alloy. Optical indicators use LED elements with epoxy encapsulation.

Structural Features: It features an ultra-compact design with a width of 12 mm, a spring-loaded terminal structure for tool-free wiring, front-facing status LEDs for visual operation monitoring, and a snap-in mounting structure compatible with standard DIN rails.

Working Principle: The terminal is installed at the end of an EtherCAT terminal chain to absorb reflected E-Bus signals and eliminate signal echo interference. It provides electrical termination for the differential E-Bus transmission line, ensuring stable and error-free data communication between the bus coupler and all connected terminal modules.

Installation Requirements: Install the unit on standard 35 mm DIN rails at the rightmost position of the EtherCAT terminal chain. Ensure wiring stripping length meets the 8–9 mm specification, and verify firm contact of all terminal connections after installation.

Precautions for Use: Do not operate the unit beyond the specified temperature and humidity ranges. Avoid exposure to corrosive gases or conductive dust. Do not remove or damage the housing during operation. Perform installation and maintenance only by trained technical personnel, and ensure power is disconnected before wiring or disassembly.
