Figure 19 - 1715-TASIB16D and 1715-TADIB16D Digital Input Termination Assemblies
The simplex termination assembly routes the input signals to one input
module. In duplex arrangements, the input signals are routed to two parallel
modules.
See page 79
for detailed wiring instructions.
Digital Output Termination Assemblies
Digital output termination assemblies support these features:
• Provide connections for eight output channels
• Industry-standard field device connectors
•24V DC operation
• Provide a fused field voltage supply to the module
There are two types of digital output termination assemblies:
• A 1715-TASOB8DE digital output, 24V DC, 8-channel, simplex TA that
provides termination for 8 digital output channels and mates with one
1715-OB8DE digital output module
• A 1715-TADOB8DE digital output, 24V DC 8-channel duplex TA that
provides fault tolerant operation for 8 digital output channels and mates
with redundant 1715-OB8DE digital output modules
