Using the Onboard Digital Inputs
Digital inputs are necessary for status monitoring or pulse counting applications.
Status monitoring can help you prevent equipment damage, improve
maintenance, or track security breaches. Some common status monitoring
applications are monitoring the closed/open positions of breakers, on/off status of
generators, armed/unarmed conditions in a building alarm system, and
over/under pressures of transformers.

The meter has eight status input ports. The function of each status input is
controlled by a Digital Input module; this module tells the meter how to interpret
incoming signals. Digital Input modules can be linked with other modules for
counting status changes.
