Product Specifications

brand name Allen-Bradley

The Allen-Bradley 20B-ENC-2

The Allen-Bradley 20B-ENC-2 is an encoder interface kit designed for use with the PowerFlex 700 series of drives. It is a component that interfaces with the encoder, which is a device that measures the position or movement of a mechanical system, and provides the necessary signals to the drive for control and monitoring purposes.

Technical Specifications

The 20B-ENC-2 is designed to operate with a supply voltage of 12 volts DC, with a maximum current draw of 250 milliamps. It supports differential encoder signals and is internally mounted. The encoder interface kit is designed for use with the PowerFlex 700 series of drives, which are known for their high-performance and flexibility in industrial automation applications.

Alarm/Error Codes

The 20B-ENC-2 does not have a specific list of alarm or error codes provided in the available documentation. However, it is likely that the drive itself would report any errors or alarms related to the encoder interface, and the specific codes would depend on the drive model and configuration.

User Manuals

The user manuals for the 20B-ENC-2 are not readily available online. However, the user manuals for the PowerFlex 700 series of drives, which the 20B-ENC-2 is designed for, are available from Allen-Bradley and other authorized distributors. These manuals provide detailed information on the installation, operation, and troubleshooting of the drive and its components, including the encoder interface kit.


Troubleshooting the 20B-ENC-2 would typically involve checking the power supply, ensuring that the encoder signals are properly connected and configured, and verifying that the drive is properly configured to use the encoder interface. The user manuals for the PowerFlex 700 series of drives provide detailed troubleshooting procedures for common issues.


The 20B-ENC-2 does not have specific programming requirements as it is a hardware component designed to interface with the encoder and the drive. The programming of the drive itself would typically be done using the drive's programming software, which is usually provided by Allen-Bradley or other authorized distributors.


The installation of the 20B-ENC-2 involves mounting the encoder interface kit internally within the drive and connecting the encoder signals to the appropriate terminals on the drive. The user manuals for the PowerFlex 700 series of drives provide detailed installation procedures for the drive and its components, including the encoder interface kit.
