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.

The function of each status input is controlled by the Digital Input modules DI-S1 to DI-S8. (Eight Counter modules for counting status changes and an External Pulse module for resetting them are included with the Digital Input framework.)

NOTE

The Digital Inputs on the Optional I/O card are controlled by the Digital Input modules I/O-S1 to I/O-

S8. However, on the Optional I/O card itself, the inputs are labelled DI1 to DI8

The settings in the Digital Input modules are as follows:

Setup Register	Available Settings	Creation Default	Description
Input Mode	Pulse or KYZ	Pulse	Complete pulse or KYZ transition pulse
EvLog Mode	Log Off or Log On	Log Off	Whether or not to log status changes in the Event Log
Debounce	0 to 65.25	0.010	Mechanical contact bounce, in seconds
Polarity	Non-Inverting or Inverting	Non-Inverting	Non-inverted (or level) pulse
