I/O Overview
Your meter has onboard digital I/O which can be increased by adding optional digital
and analog I/O modules to expand your meter’s I/O capabilities.
Your meter base has:
•
3 digital inputs
•
1 form A digital output
•
2 energy pulsing LEDs (one visible, one infrared)
You can view information about your meter’s I/O through the display and webpages,
and configure your meter’s I/O using ION Setup.
NOTE:
The digital outputs can handle voltages less than their specified maximum. For
higher voltage applications, use an external relay in the switching circuit.
Input/output ION modules
ION modules are used to configure your meter’s digital or analog inputs/outputs (I/O).
You need to configure the following ION modules in order to use the meter’s digital or
analog I/O.
•
Digital input: uses the Digital Input module, which tells the meter how to interpret
incoming signals.
•
Digital output: uses one of three ION modules depending on the application.
◦
Digital Output module: monitors a change of state to control relay operation via
a hardware output device.
◦
Pulser module: transfers high-speed pulses to a hardware pulse counting device
that is used to track energy usage.
◦
Calibration Pulser module: integrates instantaneous power inputs, then outputs
high-speed pulses to an LED that can be monitored for energy accuracy
verification.
NOTE:
All of these modules can act as intermediaries between the physical
hardware port and the other modules in the meter. They define the characteristics
of the outgoing signals.
•
Analog input: uses the Analog Input module, which tells the meter how to interpret
an incoming analog voltage or current signal from transducers.
•
Analog output: uses the Analog Output module to deliver a continuous direct
voltage or current analog signal to transducers.
Input/output ION modules, ports and labels
You can configure the Digital Output, Digital Input, Analog Input, Analog Output, Pulser
and Calibration Pulser ION modules to specify which port handles the outgoing or
incoming signals.
To assign a port to one of these modules, simply modify the Port setup register by
picking a port from the enumerated list.
The following tables describe the ports that can be configured to handle outgoing or
incoming signals:
