MDS SD Radios

MDS SD Series radios, including the SD9 and SD4 models, provide reliable licensed narrowband wireless communication for long-distance industrial applications. Designed for mission-critical environments, these radios are commonly used in utilities, oil and gas, water and wastewater, and other infrastructure networks where dependable data transmission is required. Their licensed operation helps reduce interference and supports consistent performance over extended distances.

MDS SD radios are available with Ethernet and serial interfaces, or serial-only configurations, allowing seamless integration with a wide range of field devices and control systems. This flexibility supports multiple industrial communication protocols, including Modbus TCP, making the SD Series suitable for both modern Ethernet-based systems and legacy serial networks. DIN rail and standard mounting options further simplify installation in control panels and field enclosures.

Built to operate in harsh and hazardous environments, MDS SD Series radios are engineered for durability and long-term reliability. Their rugged construction and industrial ratings make them well-suited for remote installations where environmental conditions, regulatory requirements, and continuous uptime are critical considerations.
