T9300 I/O Module Base Unit AADvance

The 9300 I/O module base unit connects the processor to I/O modules. You can install up to three modules on a base unit.

The base unit will also allow you to fit the same number of termination assemblies in different combinations. For, example, you can fit three simplex termination assemblies; or one dual and one simplex together, or one triple termination assembly.

The combination will depend entirely on your required configuration.

The I/O base unit incorporates the following features:

• Provides connection for one, two or three input/output modules depending on the redundancy requirements

• Has a polarized connection with a termination assembly that gives connection for the field input/outputs

• Routes power to the I/O modules from the processor base unit

• Routes common processor commands to the I/O modules

• Routes responses between the I/O modules and processors
