1785-SO036C-EN-P - April 2002
1771 I/O modules The 1771 series I/O modules offer digital, analog, and
special-requirement modules. The 1771 I/O modules feature a wide
range of:
• signal interfaces to ac and dc sensors and actuators
• I/O densities with as many as 32 I/O points per module
• signal levels, including standard analog inputs and outputs and
direct thermocouple and RTD temperature inputs
When you select 1771 I/O modules, you must also select:
• chassis
• power supply
• adapter module (if in remote chassis or Extended Local chassis)
For a selection chart of available 1771 I/O modules, see page 38.
For more information about the family of 1771 I/O modules, see the
following publications:
See www.automation.rockwell.com/encompass for additional
1771 I/O modules offered through the Encompass program.
Features:
• broad range of signal interfaces to
ac and dc sensors and actuators
• isolated inputs and outputs for use
in applications such as motor
control centers where individual
control transformers are used
• optical coupling and filter circuitry
for signal noise reduction
• wide range of analog signal levels,
including standard analog inputs
and outputs, direct thermocouple
inputs, and RTD temperature inputs
• analog devices with up to 16-bit
resolution
