Woodward IKD 1 Digital I/O Expansion Board
Source: | Author:kongjiang | Published time: 2026-05-21 | 0 Views | 🔊 Click to read aloud ❚❚ ▶ | Share:
IKD 1 is an intelligent expansion module, which is used to increase the number of digital I/O of Woodward easYgen series controllers and GCP-31/32 suite (equipped with SC10 or SC09 options). One or more IKD 1 units can be connected to the generator set controller. Each input can be configured with name, alarm level, normally open/normally closed setting and delay. The configured name and rank will be displayed on the screen of the connected controller. The output relay of IKD 1 is controlled by the CAN bus of the main controller, and the configuration work is directly completed by the relay manager of the main controller and transmitted to IKD 1. If complex configuration or batch setting of similar units is required, it is recommended to purchase dedicated direct configuration cable (DPC) and supporting software. The module provides 8 configurable digital alarm inputs and 8 C-relay outputs with dry contacts, and each input has independent delay. The communication is based on CAN bus, with high-precision microprocessor technology, and has been certified by CE and UL/cUL. In a typical application scenario, IKD 1 reads the digital input status and reports it to the control unit through CAN bus. The control unit can display alarm information and respond according to the set level. At the same time, the control unit independently programs and controls each relay of IKD 1 through the relay manager, and the logic command can be configured in combination with internal events and digital input status from IKD 1.

APPLICATIONS

The IKD 1 is a smart solution to increase numbers of digital I/O’s to Woodward easYgen series controllers and GCP-31/32 packages equipped with option SC10 or SC09. It is possible to connect one or more IKD 1 units to the genset controllers (see table Related Products below).

Each of the inputs can be assigned a name, alarm class, NO/NC configuration and time de lay. The name and class are displayed on the connected genset controller’s display.

The IKD 1 output relays are controlled over the CAN bus connection from the main genset controller. Configuration of the IKD 1 is performed through the relay manager in the main controller and transmitted to the IKD 1.

A direct configuration cable (DPC) and software can be purchased for use with a PC or laptop and may be advisable for extensive configuration applications or where several similar units are to be set up.

DESCRIPTION

Features   

• 8 configurable discrete alarm inputs 

 • 8 configurable FORM C relays with potential free contacts 

 • Configurable delays for each input 

 • CAN bus communication 

 • The discrete inputs transfer their status via CAN bus to the control unit. 

 • The control unit evaluates the status of these discrete inputs coming from the IKD 1 and depending on the configuration of the control unit, will take the appropriate action. 

 • The control unit can send commands via the CAN bus to remotely control the output relays of the IKD 1. 

 • The IKD 1 can be used with other manufacturer's controllers. Consult product manual 37135 for information regarding the address assignments of the CAN bus interface.

TYPICAL APPLICATIONS

The digital inputs are read by the IKD 1 and transferred via the CAN bus to the control unit (incl. alarm class). Each alarm input may have a delay as well as the control logic (NO/NC) configured individually during set up. The status of the alarm input is monitored in the control device and will show the alarm text in its display. The alarm class assigned in the control device evaluates the alarm input and reacts accordingly.

The control device’s relay manager controls the IKD 1 relays. The control logic for each IKD 1 relay can be programmed individually in the control device. Logical commands can be configured using internal events as well as the status of the digital inputs coming from the IKD 1.

If a discrete input on the IKD 1 is enabled, the control device displays a text message and the control functions of the alarm class are executed (refer to all manuals relating to the control device). The control device must operate the IKD 1 relays.
