Using the Onboard Digital Outputs
Digital outputs are used for hardware relay control or pulse counting applications.
For example, an ION meter’s digital outputs can provide on/off control signals for
capacitor banks, generators, and other equipment. The digital output ports can
also send out status signals or kWh pulses, if the receiving device determines
energy usage by counting pulses.

The meter provides three Form C mechanical relays and four Form A digital (solid-
state) relays. The four Form A digital relays are suitable for performing end of
interval pulsing, load control and alarm annunciation. All digital outputs can
deliver a continuous signal or a pulse. (Contact Power Measurement for complete
information regarding relay applications.)

These outputs can be controlled by Digital Output modules, Pulser modules, or
Calibration Pulser modules, depending on the application. For relay and control,
the Digital Output module is used. For pulsing applications, the Pulser and
Calibration Pulser modules are generally used. 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.

Output Modules
Both the Form A and Form C relays can be controlled with Digital Output
modules, Pulser modules, or Calibration Pulser modules. By default, six Digital
Output modules (labeled DO-D1 to DO-D3 and DO-R1 to DO-R3) are already
created for this purpose. You can either use these modules, or create and configure
other modules to control the output ports.
