Woodward LinkNet Series 9905-973 8-Channel Relay Output Module
9905-973 belongs to the Woodward LinkNet series of 8-channel relay output modules, which are matched with I/O expansion modules for turbine control systems. They are installed in a rail mounted manner and communicate with the host controller through the LinkNet bus. They are discrete output units that are matched with gas/steam turbine control systems.
Product features
- 8 independent relay dry contact output channels, each channel electrically isolated, suitable for driving on-site solenoid valves, alarm circuits, interlock circuits, with strong anti-interference ability.
- LinkNet dedicated bus interface, directly connected to Woodward turbine control system, stable communication, supports module fault diagnosis, panel LED indicator lights, intuitively view channel operation and fault status.
- Standard DIN rail installation, quick assembly inside the cabinet, pluggable wiring terminals, easy maintenance and replacement.
- Relay contact isolation isolates the control system from the on-site strong current circuit, avoiding on-site interference and surge damage to the main control unit.
- Wide temperature working range, suitable for harsh cabinet conditions such as high temperature, humidity, and high vibration in power plants and oil and gas plants.
