Westermo Data Communications has released a new range of high performance industrial radio modem’s to provide wireless links between serial devices over long distances and in demanding industrial applications. The ELPRO 455U series form a robust and secure platform to provide high-speed wireless connectivity via licensed radio channels. Designed and built for systems applications requiring the higher level of reliability offered by licensed radio channels, the 455U’s can connect to PLC’s, HMI’s, DCS, data acquisition, video devices and industrial PC’s.
Designed for a broad range of applications, especially within the utility industries, the 455U-D can be used for example to connect remote PLC’s in a SCADA system within the water and waste water industry, provide wireless links to substation Remote Terminal Units (RTU) for the electricity industry or to access field data loggers units in oil and gas industries. The 455U’s can be configured as an access point, client/station, a bridge, repeater or a router. The unit can be used for alarm output, powering up local devices or as a hot redundant standby.
The 455U’s are capable of transmitting data at up to 19.2 Kb/s over distances of 30-100km (depending on terrain and local radio regulations). The 455U has user configurable RF power of 0.5 to 5W , and cover the frequency range 380 – 512 MHz. The data transfer is secured using military grade 128-bit AES encryption.
The 455U series utilise Multiple Device Connectivity (MDC) functionality. With two data ports, the 455U modem can handle two independent connectivity applications simultaneously. Several intelligent networking modes are provided to enable connection to a wide variety of devices including wireless mesh multi-hop repeater networking. The 455U also provides Optimal Path Routing and protocol-specific wireless optimisation for Modbus, DNP3, DF1 and Profibus communications. Bell 202, V23, and 600 ohm audio are supported.
The 455U can be used in operating temperatures of –30 degC to 60 degC and in humidity of 99%. A built-in battery management circuit protects against an uncertain power supply. The unit is extremely easy to use with free configuration and diagnostics software, that can be run either with a direct connection or over the radio.
