Woodward 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.

Function: Receive instructions from the main control unit, output 8 relay dry contacts, and complete the on/off control of on-site solenoid valves, alarm indicator lights, interlock switches, fans, valves, and other equipment; Implement isolated driving of control system logic signals to peripheral field devices; Feedback channel status and fault diagnosis information are transmitted back to the main control, completing unit interlocking protection, alarm output, auxiliary equipment start stop control, and sharing the switch output load of the main control module.

Product features
1. 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.
2. 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.
3. Standard DIN rail installation, quick assembly inside the cabinet, pluggable wiring terminals, easy maintenance and replacement.
4. 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.
5. 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.
