1715-IB16D Digital Input Module

The digital input interface is a combination of digital input modules and
termination assemblies. The 24V DC isolated digital input modules have a
flexible and fail-safe design. The 1715-IB16D interfaces 16 digital input channels
and can be configured in RSLogix programming software as simplex or duplex
by selecting one of the two available termination assemblies and the required
number of modules.
IMPORTANT When the 1715-IB16D digital input module is used with the 1715-
TASIB16D simplex termination assembly, it is nonisolated.
The 1715-IB16D digital input module features are as follows:
• Flexible, modular construction for user-configured I/O applications
• 16-channel connection capability
• Suitable for simplex, duplex connections, and fault tolerant applications
• Independent, galvanically isolated input channels
• Built-in diagnostic testing and independent watchdog facility
• Module removal and replacement online and, when in Duplex mode, no
interruption of the signal inputs
• Input voltage data is provided for line monitoring and field fault
detection
• Timestamp value per channel recording the time of any transition of
state from ON->OFF or OFF->ON. Note that this value will be overwritten
with each change of state of the input.

1715-OB8DE Digital Output Module

The digital output module interface consists of a combination of digital output
modules and digital output termination assemblies. Each module provides 8
isolated output channels and plugs into one position of the I/O base unit and a
corresponding termination assembly. Digital outputs can be configured as
simplex or duplex.
The 1715-OB8DE digital output module has a flexible, fail-safe design, with
eight field output channels. The module output can be up to 1A continuous for
each channel.
