Digital inputs
Digital input applications
Digital inputs are typically used for monitoring the status of contacts, such as status
contacts on circuit breakers.
They can also be used for pulse counting or input metering applications, such as
WAGES (water, air, gas, electricity, steam) monitoring, or conditional energy
applications, or IRIG-B time synchronization.
IRIG-B time synchronization
You can use a digital input to synchronize the meter time to an IRIG-B time source.
You can connect an IRIG-B time source to one of meter’s digital inputs for IRIG-B time
synchronization; for improved accuracy use the digital inputs on the meter base. For
IRIG-B time synchronization, you must configure both the meter’s digital input and the
meter’s clock.

You can use ION Setup to configure your meter’s digital inputs.
Digital inputs are available on your meter. You can add more digital inputs using
optional I/O modules.
1. Start ION Setup.
2. Open the Setup Assistant for your meter.
3. Navigate to
I/O > Digital Inputs
. The tabs correspond to each digital input. Click on
the tab for the digital input you want to edit.
4. Configure the digital input by selecting the parameter and clicking
Edit
.
5. Once the parameter has been configured, click
OK
to save the setting to the meter.

Description
Input Mode
Pulse, KYZ, A/C,
IRIG-B
1
Specifies how the meter processes the signal:
•
Pulse: the meter counts an entire pulse (from
off-on to on-off) as one input.
•
KYZ: the meter counts a transition (from off-
on or from on-off) as one input.
•
A/C: the meter detects analog signals where
the ON condition is based on the presence of
an AC signal
•
IRIG-B
1
: the meter detects an IRIG-B time
synchronization signal.
Polarity
Inverting/Non-Inverting
Specifies if the signal from the digital port is
inverted or not inverted.
Debounce
0.000 - 1.000
Specifies how long (in seconds) the signal must
remain in a state to be considered a valid state
change.
Port
Defined by your meter’s
hardware
Your meter’s physical digital input port.
1
IRIG-B can only be connected to one of the digital inputs located on the meter base, not an option
module. You must also configure your meter’s clock to use IRIG-B time synchronization.
