Since environmentally controlled telecom closets aren’t common ® on the shop floor, RJ-Lnxx switches are built to thrive in adverse conditions. Enclosures are eliminated, and network design is simplified, while your business enjoys the highest level of data integrity Ethernet Switches Features PLC • Extended temperature ranges DRIVE • Environmental Sealing PC • Vibration Resistance HMI • Industrial Mounting Methods REMOTE I/O • Hazardous Duty Ratings Ethernet networks consist of a star topology—all transmissions pass through a central device. The repeater hub is the simplest form of such a device, but has limitations in industrial applications: • If more than one Ethernet device transmits at the same time, a data collision will occur, forcing each station to retransmit in order to deliver its message • Hubs must transmit messages from all ports to reach the intended receiver, creating inefficient bandwidth usage Ethernet switches, however, allow all devices to transmit simultaneously, without collision. This is essential for enabling deterministic delivery of time- critical information. Switches are intelligent devices, keeping track of device locations; this allows messages to be transmitted only from the necessary port, leading to improved network performance Machine Mount Switch Specifications Electrical Required Power 10-30V DC Power Consumption 1.9 Watts Typical The ENHSA is an 8 port switch designed to operate without the need for any Network Isolation 1200V RMS for 1 min. type of enclosure.
