Analog Input Termination Assemblies
Analog input termination assemblies support these features:
• 16 input channels for a simplex/duplex configuration
• Industry-standard field device connections at the terminal blocks
• Analog input channels with a high reliability 120

precision resistor
termination per input channel
• Individually-fused channels with over voltage input protection
There are two types of analog input termination assemblies:
• A 1715-TASIF16, 16-channel simplex TA that provides termination for
16 single-ended analog input channels and mates with a single 1715-IF16
16-channel analog input module
• A 1715-TADIF16, 16-channel duplex TA that provides termination for 16
isolated analog input channels and mates with up to two 1715-IF16
16-channel analog input modules
