ENGLISH EMOSAFE EN-95 Product Datasheet Network Isolator for Industrial Applications 1 FEATURES AND ADVANTAGES High-Performance Gigabit Ethernet Network Isolator 4.0 kV AC dielectric strength 5.6 kV DC dielectric strength DIN EN 50155 compliant ISO 11801 Class D Ethernet performance Extremely low insertion loss ESD protection: suppression of transient over voltages on the signal lines Suitable for devices with a supply voltage of up to 250 VAC RoHS compliant Socket and DIN rail adapter available as accessories 2 GENERAL DESCRIPTION EMOSAFE EN-95 network isolators interrupt the electrically conductive connection (wires and shield) be- tween devices that are connected to each other via copper-guided Ethernet cabling. They prevent equipo- tential bonding currents and protect connected devices and their users from transient over voltages that PD1157-V20 Page 1 of 10 2019 EMO Systems GmbH EMO Systems GmbH Rungestr. 19 10179 Berlin Germany Phone: +49-30-4000-475-80 Fax: +49-30-4000-475-90 www.emosystems.de/en have been directly or inductively coupled into the network cable because of installation errors, lightning, switching operations, or electrostatic discharges. The EMOSAFE EN-95 network isolator protects connected terminal devices against the hazards described in section 3. The EN-95 fulfils all design requirements of DIN EN 50155. The EMOSAFE EN-95 is a powerful and compact Gigabit network isolator characterised by outstanding Ethernet performance and very high dielectric strength. The EN-95 is equipped with a TVS diode circuit that effectively limits the differential interference signal level on a wire pair. Differential voltage peaks can be caused by malfunctions of connected devices or by electrostatic discharges during the plugging process. The network isolator EMOSAFE EN-95 passes high-frequency alternatingsignals according to the principle of electromagnetic induction in the frequency range used for data transmission. Because of this transmis- sion principle, the EN-95 does not require its own power supply. Driver installation is not required. 3 APPLICATIONS 3.1 USER PROTECTION Galvanic isolation of the Ethernet interfaces of electrical devices or systems where users must be pro- tected against dangerous leakage currents in accordance with standards. 3.2 EQUIPMENT PROTECTION Applications, in which valuable devices or those requiring special protection need to be protected against ripple, mains hum, and surge voltages from the network periphery. 3.3 MEASUREMENT EQUIPMENT Electrical measuring and monitoring equipment, which needs to be protected against external voltages and interference voltages arising from the Ethernet periphery. 3.4 POTENTIAL DIFFERENCES (INDUSTRIAL PLANTS, BUILDING AND RAILWAY SYSTEMS) Prevention of equipotential bonding currents in computer systems that are galvanically connected to each other via Ethernet cabling over greater distances.
