Annunciator Expansion Module

Overview

The expansion module (Brain+) is an additional module available from EMIT that expands the amount of inputs and outputs available for the Brain. The expansion module adds 12 thermocouples, 8 analog inputs, 6 digital outputs, and 2 analog outputs.

Configuring Expansion I/O

If the expansion module is present on the communications bus along with a Brain, then under the input setups the available inputs will be expanded by the amount available on the expansion module. The inputs and outputs show up as if the Brain itself simply has more I/O, and the expanded I/O can be configured in the same way as any other I/O.

The inputs on the expansion module begin at the next available index, and are appended with “A” or “B”, depending on the switch on the corner of the expansion module.

Expansion Module Functionality

The inputs and outputs on the expansion module will function the same as on the Brain- the inputs can be set up for any class and action, and if configured as a shutdown will shut down the engine when faulted. The additional inputs will also show up in the datalog list to view for datalogging.

Once the expansion module appears on the communication bus, the Brain will expect it to be present indefinitely until the panel is powered off. If the expansion module ever goes from present to not present, because of hardware or power failure, the Brain will fault out with the shutdown code "Expansion module no longer present".
