Providing precise signal conversion down to 0 to 200 mA output profiles and high-voltage isolation, the unit ensures deterministic command execution across turbine governing hardware. Its high-current output relay contacts maintain steady actuation dynamics, mitigating voltage drop across extended field wiring trunks during high-power load changes.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What power supply range is required to operate the Woodward 9905-973 module?\u003c\/p\u003e\n\u003cp\u003eA: The module requires an incoming DC power supply voltage between 18 and 32 VDC, consuming 14 W of operating power under standard conditions.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum allowable stub length for field communication wiring?\u003c\/p\u003e\n\u003cp\u003eA: The maximum stub length permitted for network branch connections is 300 mm within the operating temperature range of +40 to +85 deg C.\u003c\/p\u003e\n\u003cp\u003eQ: How many independent control channels are available on this module?\u003c\/p\u003e\n\u003cp\u003eA: The module provides eight individually managed relay channels rated up to 24 VDC at 16 A per output circuit.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMount the module securely inside an IP54 or NEMA-rated metal enclosure to protect internal relay contacts from ambient airborne contaminants.\u003c\/li\u003e\n\u003cli\u003eObserve strict isolation between 24 VDC control power lines and high-current AC output wiring to prevent induced inductive noise.\u003c\/li\u003e\n\u003cli\u003eLimit communication drop connections to a maximum stub length of 300 mm from the primary Linknet network trunk.\u003c\/li\u003e\n\u003cli\u003eEnsure all field wiring shields are grounded at a single earth point to maintain noise immunity across the speed sensing input and actuator output lines.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Woodward","offers":[{"title":"Default Title","offer_id":50692279468284,"sku":"9905-973","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/9905-973.jpg?v=1785116692","url":"https:\/\/www.electronicplc.com\/products\/woodward-9905-973-linknet-8-channel-relay-module","provider":"Electronic PLC","version":"1.0","type":"link"}
