7272 ControlLogix EnDat Interface Module

7272 ControlLogix EnDat Interface Module
  • Two-channel bi-directional EnDat interface for position encoders.
  • Provides read/write access to encoder parameters
  • EnDat clock speed 100KHz to 2 MHz
  • Onboard diagnostics monitor and report errors
  • Latch inputs for capturing the scaled data value
  • PLC time can be sent to the module to generate an interpolated (look ahead) data value
  • Incorporates Rockwell Automation licensed technology for 100% compatibility with 1756 PLC

    7272 ControlLogix EnDat Interface Module

    Digital drive systems and feedback loops with position encoders for measured value acquisition require fast data transfer with high transmission reliability from the encoders. Further data, such as drive-specific parameters, compensation tables, etc. must also be made available. For high system reliability, the encoders must be integrated in routines for error detection and have diagnostic capabilities. Now adding this technology to your ControlLogix PLC is simple thanks to AMCI's 7272 (2) channel EnDat interface module.

    The AMCI 7272 PLC module for ControlLogix was developed for applications requiring a direct interface to encoders that output EnDat data. Plus this card incorporates Allen-Bradley licensed technology for guaranteed compatibility with A-B Series 1756 I/O chassis.

    The ControlLogix EnDat interface module from AMCI is a digital, bidirectional interface for encoders. It is capable both of transmitting position values
    from incremental and absolute encoders as well as transmitting or updating information stored in the encoder, or saving new information. This module is capable of connecting up to two independent EnDat output encoders/sensors with max 48-bit resolution for position. This module also has two latching inputs, one for each channel, which can be used to capture the sensor’s data.
