3.2.6 AI/DI Module

When the AI/DI expansion card installed in the ECC500 has insufficient space for AI/DI data
collection, you can connect an AI/DI module to the AI/DI expansion card using an RS485 bus.
The eight AI/DI input ports on the module can collect more AI/DI signals. The AI/DI module
can be mounted in a 19-inch rack or on a wall.
