Allowing terminals equipped with a serial interface to be connected to Ethernet networks, Belden’s Hirschmann product range now includes four IOLAN DS series converters from Perle Systems. All of the models have software-selectable RS 232/422/485 interfaces as well as an Ethernet port – or two Ethernet ports in the case of the rack variant. In addition, they support various protocols for serial data transmission, including Modbus TCP Gateway, Raw Serial Data over UTP, IPv4 and IPv6. The Perle Device Manager facilitates device configuration. The housings are made of metal, and have fanless cooling. Furthermore, all models meet IEC 60950-1safety and EN 61000 EMC standards. As the four converters have a different number of serial interfaces as well as different bandwidths, security functions, protection standards, temperature ranges, and special approvals, it is easy for the users to find the ideal solution for their application – whether it is in a factory, in process and building automation or in the energy sector. The compact IOLAN DS1 T, which is designed to meet the requirements of protection standard IP40, is equipped with a serial DB9M interface as well as a Fast Ethernet port with RJ45 connection. Its temperature range is from -40 to 70°C. Power is supplied via a terminal block, and can range from 9 to 30 VDC. Thanks to its compact dimensions – 91 x 89 x 24 mm (h x w x d) – the converter can be mounted directly on a wall or on a top-hat rail using an optional adapter. The IOLAN SDS4 HL, which is approved for use in Ex Zone 2, additionally features an extensive range of security functions such as RADIUS authentication, SNMPv3, and IPSec VPN Gateway. This converter, which measures 113 x 81 x 28 mm, also has four serial interfaces for RJ45 ports. The PCBs have a special conformal coating to provide protection against condensation. Featuring three serial RJ45 interfaces, the IOLAN SDS3 M is equipped with a V.92/V.90 modem that enables it to be connected to wide area networks. Operating over 0 to 55°C, it measures 91 x 89 x 24 mm. Finally, the IOLAN SDS16C HV is especially suited to extreme operating conditions found in transformer stations in the electricity industry. Designed for use in switch cabinets (19" housing with one HU), this IP30 converter offers 16 serial RJ45 interfaces and two RJ45 Gigabit Ethernet ports. Other features include high vibration resistance, extensive resilience to magnetic fields and electrostatic discharges (IEC 61850-3, IEEE 1613) as well as an HV power supply unit (88 - 300 VDC/85 - 265 VAC). What is more, the converter complies with the NERC CIP security standard.
