I/O configuration

The meter’s digital and analog I/O ports simplify data gathering by importing a variety of data types into a single, common system.

You need to configure the following modules in order to use the meter 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 revenue meter calibration.

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

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

    See the ION8650 Installation guide for I/O wiring instructions.

A

Onboard I/O

B

Onboard I/O

C

Expanded I/O (and serial COMs): Molex Micro-Fit 24 pin male connector

D

Optional Onboard I/O: 16 pin male connector.

E

Optional I/O Expander for serial communications and expanded I/O. For more information, see the PowerLogic I/O Expander Installation Guide.

 

Serial COMS:

COM1: RS-232 or RS-485

COM4: RS-485, depending on the options ordered for the meter.

 

Depending on the version of the I/O Expander that you ordered, you can have:

  • Eight Form A digital inputs
  • Four Form C digital outputs
  • Four Form A digital outputs
  • Four analog outputs

F

Onboard I/O breakout cable with female connector and sixteen bare-ended wires.

See your meter's Installation Guide for installation instructions.

I/O Expander for ION8650 meters

For analog or additional digital I/O with the meter, you can use an external

I/O Expander. Information for the analog and digital I/O Expander options is available in the I/O Expander Installation Guide.
