Woodward 9907-023 Forward Acting Speed Control

Description:

These Woodward 2301A controls accept either a high-voltage or a low-voltage power source. The low voltage models operate on 20 to 40 Vdc, and the high voltage models operate on either 88 to 132 Vac or 90 to 150 Vdc. Both the lowand high-voltage models require a power capacity of 15 W minimum.

All shielded cable must be twisted conductor pairs. Do not attempt to tin (solder) the braided shield. All signal lines should be shielded to prevent picking up stray signals from adjacent equipment. Connect the shields to the control terminals as shown in Figure 2-1 and in the plant wiring diagram (Figure 1-2). Wire exposed beyond the shield should be as short as possible, not exceeding 50 mm (2 inches). The other end of the shields must be left open and insulated from any other conductor. Do not run shielded signal wires with other wires carrying large currents. See Woodward application note 50532, EMI Control for Electronic Governing Systems, for more information.

A contact to override the failed-speed-signal circuit can be installed in series with terminal 18 and the dc power to the control. When the contact is open, the control operates normally, turning the control output off in the event of a loss of speed signal. Closing the contact overrides the failed-speed-signal circuit as may be required for start-up.

The module provides communication interfaces for seamless integration with supervisory control and data acquisition (SCADA) systems or other control networks. It supports industry-standard protocols, enabling remote monitoring and control of parameters.

The module is designed for easy installation and configuration, simplifying the integration process into existing control systems. It offers user-friendly interfaces and intuitive configuration options, reducing setup time and effort.
