Woodward 2301E Digital Load Sharing and Speed Controller four modes of operation

The 2301E includes

 1 load cell circuit

 1 actuator driver, 4-20 mA, 0-20 mA, 0-200 mA or PWM

 1 MPU speed sensor

 1 configurable analogue output

 2 configurable analogue inputs

 8 discrete (switching) inputs

 4 discrete (relay driver) outputs

The 2301E has an operating temperature range of -40 to +70 °C (-40 to +158 °F).

The Woodward 2301E provides load sharing and speed control for generators driven by diesel or gas engines.

With the flexible configuration software in the 2301E hardware,

Application variations can now be selected using an external computer (PC).

Applications can be changed to accommodate engine speed ranges, gear tooth counts,

and forward and reverse selections with a simple software setup.

The 2301E is capable of communicating using the Modbus® * RTU protocol,

operating as a Modbus slave device via an RS-422 driver.

The 2301E has four modes of operation:

Speed Control

Provides a wide range of dynamic flexibility. Can be used for pumps or compressors.

Remote 4-20 mA speed reference via configurable analogue input.

Asynchronous Load Sharing

Compatible with most existing analogue load sharing speed control systems.

Now with soft loading and unloading capabilities.

Dropped Base Load

Adjustable load control using discrete lift contacts.

Constant Speed Base Load

Provides constant load level operation against the mains bus. 

Load settings can be fixed or changed using discrete raise and lower inputs or a remote 4-20 mA input.
