I/O Termination Assemblies
I/O termination assemblies are inserted into the I/O base units. There are eight
types of termination assemblies (two for each module) depending on the
architecture of your system and the I/O modules you are going to use.
Digital Input Termination Assemblies
Digital input termination assemblies support these features:
• 16-channel simplex TA provides termination for 16 digital input channels
• Industry-standard field device connections at terminal blocks
• 24V DC digital input channels with a load of 5.11 k
 per input channel
• Individually fused channels with over voltage input protection
There are two types of digital input termination assemblies:
• A 1715-TASIB16D, 16-channel simplex TA that provides termination for
16 digital input channels and mates with a single 1715-IB16D digital
input module
• A 1715-TADIB16D, 16-channel duplex TA that provides termination for
16 digital input channels and mates with up to two 1715-IB16D digital
input modules
