Woodward 2301A Speed Control
4-20 mA/1-5 Vdc Speed Set

Applications:
The 2301A Full Authority Speed Control sets the speed or load of a diesel engine, gas engine, steam turbine, or gas turbine according to the demand of a process or a computer control signal of 4–20 ma or 1–5 Vdc.
The unit provides isochronous operation, with droop control available through an externally-wired potentiometer. The isochronous mode is used for constant speed of the controlled prime mover as long as it is able to provide power to satisfy the load. Droop control is provided when parallel-bus operation is required. The Full Authority Speed Control is compatible with Woodward SPM-A synchronizers, load sensors, and other power generation controls. These auxiliary controls can be added to the system at any time, connecting the auxiliary or SPM inputs to the 2301A Speed Control. The control is available for forward- or reverse-acting applications.
High-voltage models accept 88 to 132 Vac or 90 to 150 Vdc. Low-voltage models accept 10 to 40 Vdc supply.
Programmable Logic Control (PLC) is easily adapted to engine control with the use of the 4–20 ma speed setting input. The low-limit setting can prevent engine shutdown, even with loss of the PLC signal. Reverse-acting controls may be teamed with EGB or PG-EG governor/actuator for a mechanical ballhead backup.
