Woodward 8440-2028 IKD 1 Digital I/O Expansion Module

The Woodward 8440-2028 provides industrial system builders with a modular, plug-and-play solution for expanding hardware I/O boundaries without upgrading to entirely different main processing platforms. When a power generation configuration demands more field feedback channels—such as supplementary fuel level switches, enclosure temperature breakers, or ventilation status flags—this IKD 1 card acts as a distributed collection node.

Rather than complicating the core panel layout with dense homerun wiring tracks, the 8440-2028 reads local digital inputs and streams the states directly over an isolated CAN bus interface.The main easYgen host unit processes these remote data lines, executing customized LogicsManager criteria and triggering the module’s onboard Form C relays. Field setup is streamlined through manual onboard DIP switches that control localized hardware addressing, completely eliminating the need for separate software calibration utilities during initial field startup.

• Distributed Network Scaling: Up to two 8440-2028 modules can be cascaded onto a single master generator network loop, instantly providing 16 extra discrete inputs and 16 additional output relays.

• Centralized Configuration Routing: Eliminates localized programming requirements. Input names, debounce filtering parameters, alarm delays, and normally open/closed states are configured inside the master easYgen control interface.

• Robust Electrical Isolation: Features galvanic protection on all power paths, discrete lines, and CAN communication terminals, blocking destructive high-voltage inductive kicks from crossing backplane loops.

• Form C Relay Versatility: The SPDT (Single Pole Double Throw) output relays provide both normally open and normally closed contacts, supporting both fail-safe and fail-secure external control logic.

• Intuitive Alarm Mirroring: Any field fault registered at the 8440-2028 terminal strip is sent instantly to the central controller panel, displaying customized alarm text directly on the master HMI screen.

• Multi-Genset Power Infrastructures: Aggregates auxiliary mechanical and breaker telemetry lines for massive parallel generator groups.

• Industrial Automation & Plant Utilities: Manages remote pump, fan, and louver command loops linked to automated turbine emergency setups.

• Critical Facilities & Nuclear Backup Control: Deployed inside ruggedized emergency diesel control enclosures requiring highly isolated, redundant digital telemetry arrays.

Q1: Do I need a specialized programming cable to set the baud rate on this card?

A: No, fundamental parameters like the network node module address and the CAN communication baud rate are set manually using physical, onboard DIP switches located directly on the PCB casing.

Q2: Can the inputs on the 8440-2028 accept direct AC voltage inputs?

A: No, the 8 discrete inputs are rated for DC voltage configurations only (nominal 12/24 Vdc).Feeding alternative raw AC lines directly into these terminals will permanently damage the input isolation optical couplers.

Q3: How does the host controller react if the CAN bus cable to the 8440-2028 breaks?

A: The master easYgen unit continuously polls the 8440-2028 node via life-signal heartbeat tracking. If connection drops, the host controller registers a communication fault alarm instantly, dropping safe-mode routines based on your system safety logic.
