AMCI 7272 EnDat Interface PLC Module
for Allen-Bradley ControlLogix |
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.
