Belden has extended its Hirschmann product program to include Ethernet switches from the new RSP family. These are especially designed for use in the field-level networks of power supply companies, but they also can be used in any situation where uninterrupted communication is required, for instance for mechanical engineering projects or drives for production facilities. These extremely robust fanless switches have eleven ports, three of which can be used for SFP transceivers. These support Fast (100 BASE-FX) or – optionally – Gigabit Ethernet (100/1000 BASE-FX). The remaining eight ports can be used either for 100 BASE-TX or as a combination of four SFP transceivers and four TX ports. Additional features of these switches include comprehensive management, diagnostic and filter functions plus a variety of redundancy methods and markedly expanded security mechanisms. In addition to the standard configuration, Hirschmann also offers a version that supports highly precise synchronisation compliant with IEEE 1588v2, plus PRP (Parallel Redundancy Protocol) and HSR (High-availability Seamless Redundancy). This means that, for the first time, it is now possible to implement networks that guarantee uninterrupted data communications with the attached systems and can thus – in the case of the electricity supply industry – guarantee reliable power supplies to end customers at all times.
These switches, which comply with the standards and approvals of IEC 61850 3, IEEE 1613, EN 50121 4, NEMA TS2 and cUL 508, are remarkable for their high vibration resistance and extensive resilience to magnetic fields and electrostatic discharges, and can also withstand ambient temperatures in the range -40°C to +70°C. The supply voltage may be either 24/48 V DC or 60/120/250 V DC and 110/230 V AC.
