The NEMA TS2 standard was established by the National Electrical Manufacturers Association (NEMA) to define safe traffic control equipment. Section 2 contains the environmental and testing requirements, including guidelines for temperature (-34° to 74°C), humidity, vibration and shock.
Independent lab testing verified Comtrol’s DeviceMaster serial device servers’ and RocketLinx industrial Ethernet switches’ performance when subjected to the extreme temperatures, operating voltage and humidity fluctuation, vibration and shock commonly experienced in severe outdoor environments.
“We know how important NEMA certification is to our traffic and transportation customers,” Comtrol’s President, Bradford Beale, said about the National Electrical Manufacturers Association standard, “To show our dedication to these customers and others that require extended temperatures from -34° to 74° degrees Celsius, our standard 1, 2, 4 and 8 port DeviceMaster RTS and PRO products are compliant at no additional cost to our traffic management customers.”
These field-hardened device servers provide connectivity for a broad range of traffic and transportation applications currently used by more than 300 traffic and transportation agencies nationwide. Select models of Comtrol’s RocketLinx industrial Ethernet switches are also NEMA TS2 certified. Our customers use DeviceMaster device servers and RocketLinx switches to control and manage intelligent transportation systems (ITS) including traffic management systems, arterial and freeway management, roadside cabinet networking, and intersection management and control. Reliable and easy-to-install, DeviceMaster devicare also cost effective solutions for open road tolling (ORT), electronic toll collection (ETC), toll plazas, and parking automation environments.
“Ensuring that our products are field hardened—especially for harsh temperatures— has been a critical design objective for some time,” said Beale, “In fact, while NEMA certification requires that systems withstand temperatures of -34° C, we designed DeviceMaster and RocketLinx products to withstand -37° C, and in some cases 85° C.”
