Overview
The Woodward 9905-968 Analog Input Module is part of the LinkNet series, engineered for high-accuracy signal acquisition in harsh industrial settings. It features six isolated analog input channels, each capable of measuring 4–20 mA current signals, commonly used for sensors monitoring pressure, temperature, flow, and other process variables.
Moreover, the module supports LON (Local Operating Network) and Modbus RTU communication protocols, allowing seamless integration into distributed control systems and SCADA platforms. Its IP67-rated enclosure ensures protection against dust, moisture, and vibration, making it suitable for field-mounted applications. In addition to robust signal handling, the module operates reliably across a wide temperature range and is certified to CE and UL standards.
Therefore, the 9905-968 is widely used in power generation, oil & gas, water treatment, and manufacturing environments where precision, durability, and network compatibility are essential.
