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 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.
• 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.

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 incoming and outgoing signals.
