The 5441-629 is a Relay Interface Module designed and manufactured by Woodward for high-capacity industrial turbine governor and sequencing frameworks, such as the MicroNet and NetCon automation platforms. Containing a 5-channel relay switching array rated at 5 Amps per channel, this module serves as a ruggedized command execution bridge between delicate low-voltage microprocessor logic and high-power plant machinery fields.
HIGH-ISOLATION INTERFACE MATRIX:
The primary function of the 5441-629 is to establish a secure electrical boundary between the central processing unit and external inductive loads. The module utilizes optical isolators combined with heavy-duty galvanic separation to isolate control logic from field anomalies. This structure guarantees that transient surges, electrical shorts, or ground faults originating on external field lines are stopped at the relay barrier, preventing damage to the motherboard backplane.
FORM C FIELD LINKAGE DRIVE:
The module is populated with independent, electromechanical Form C relay circuits. Each circuit provides standard Single Pole Double Throw (SPDT) pathing, giving field technicians both Normally Open (NO) and Normally Closed (NC) dry contact outputs. This design allows for dual-state sequence wiring, ideal for governing fuel gas trip blocks, hydraulic shutoff valves, interlock safety loops, and emergency plant alarm matrices.

What is Woodward 5441-629?
The 5441-629 is a 5-Channel, 5 Amp Relay Interface Module developed by Woodward for its high-performance turbine control architectures like NetCon and MicroNet. It functions as an isolated digital output interface that translates low-voltage processor commands into high-power mechanical switching operations.
What is the benefit of the Form C relay configuration on this board?
Form C relays feature an SPDT architecture providing a common terminal, a Normally Open contact, and a Normally Closed contact. This allows a single channel to independently control alternating loop logic or manage state monitoring for critical fail-safe equipment.
How does the module handle high-current inductive flyback?
The internal circuitry incorporates built-in snubbing components and freewheeling diode paths across the relay driver networks. This absorbs the high-voltage inductive spikes created when external solenoid or contactor coils are de-energized, preventing premature arc wear on the physical relay contacts.
What is the main structural difference between the 5441-629 and the 5441-419 models?
The 5441-629 is a dedicated 5-channel, 5 Amp relay configuration optimized for higher localized current handling profiles. In contrast, models like the 5441-419 feature a denser 16-channel layout designed for widespread lower-current control distribution.
