Chapter 4 Digital I/O Operation
Termination Assemblies
There are two types of termination assemblies for the digital input modules.
The application of your system determines which termination assembly you
need:
•
1715-TASIB16D 16-channel, digital input simplex termination assembly
•
1715-TADIB16D 16-channel, digital input duplex termination assembly
Determining Output Module
Compatibility
1715 digital output modules can be used to drive various output devices. Typical
output devices compatible with the 1715 digital outputs include the following:
•
Motor starters
•
Solenoids
•
Indicators
When designing a system, do the following:
•
Make sure that the outputs can supply the necessary surge and
continuous current for proper operation.
•
Make sure that the surge and continuous current are not exceeded.
Damage to the module could result.
When sizing output loads, check the documentation that is supplied with the
output device for the surge and continuous current necessary to operate the
device.
The 1715 digital outputs can directly drive the 1715 digital inputs. The
exceptions are DC diagnostic input modules. When diagnostics are used, a
shunt resistor is required for leakage current.
For more information specifically on the compatibility of motor starters to
output modules, see ControlLogix Digital I/O Modules, publication
Termination Assemblies
There are two types of termination assemblies for the digital output modules.
The application of your system determines which termination assembly you
need:
•
1715-TASOB8DE 8-channel, digital output, simplex termination assembly
•
1715-TADOB8DE 8-channel, digital output duplex termination assembly
Using Features Common to
1715 Standard Digital I/O
Modules
The following features are common to all 1715 digital I/O modules.
Removal and Insertion Under Power (RIUP)
All 1715 digital I/O modules can be inserted and removed from the I/O base unit
while power is applied. This feature lets you have greater availability of the
