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 a single
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
