A-B 1715-A2A Module Base

I/O Termination Assemblies (TA)

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.

For this example, we only show the duplex assemblies.

• 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

• A 1715-TADOB8DE digital output, 24V DC 8-channel duplex TA that

provides fault tolerant operation for eight digital output channels and

mates with redundant 1715-OB8DE digital output modules

• 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. The channels are isolated.

• A 1715-TADOF8, 8-channel duplex termination assembly provides fault

tolerant operation for eight analog output channels through inter-module

communication and by routing the output source current from two

modules to the same field device

1715 Digital and Analog I/O modules

Your system can be configured with any combination of I/O modules, and in

either Simplex or Duplex mode. These I/O modules can be included in your system:

• 1715-IB16D 16-channel digital input module

• 1715-OB8DE 8-channel digital output module

• 1715-IF16 16-channel analog input module

• 1715-OF8I 8-channel analog output module

Power Requirements

A 24V DC power supply is required. For proper duplex operation, two power

supplies are recommended. This is not required for fail-safe safety systems but for

availability or energize-to-action systems. 

Features and Benefits

1715 redundant I/O is Rockwell Automation’s first true redundant I/O platform and off ersexceptional ease-of-use. 

It requires no user programming code or additional hardware to operate.

With support for both standard and extreme environments, 1715 I/O off ersconsiderable flexibility,

supporting multiple confi gurations and applications with a single product.

It off ersbroad support for critical applications ranging from nonsafety and both simplex and duplexconfi gurations.

The 1715 platform also includes redundant Ethernet adapters for even greater fault-tolerant capabilities and includes premier

diagnostic capabilities.
