Configuring Digital and Analog I/O

With the exception of Modbus master control of I/O, ION meters require the setup of ION modules for digital and analog I/O capabilities.

Digital Input: Digital (status) inputs can be used for monitoring external contacts or pulse counting applications, and are controlled by Digital Input modules. This module tells the meter how to interpret incoming signals.

Digital Output: Digital outputs are used for hardware relay control or pulse counting applications. The outputs can be controlled by Digital Output modules, Pulser modules, or Calibration Pulser modules, depending on the application (relay switching or energy pulsing). An example of a commonly used application for each module is listed below.

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 to verify ION revenue meter calibration.

All of these modules can act as intermediaries between the hardware port and the other modules in the meter. They define the characteristics of outgoing signals.

Analog Input: Analog inputs can measure DC signals from transducers. They are controlled by Analog Input modules.

Analog Output: Analog outputs can deliver a continuous DC signal, and are controlled by the Analog Output modules.

The following sections describe how the modules provide digital and analog data exchange among ION meters and devices that measure and collect various types of information.
