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.
Onboard I/O for the ION 8000 Series meters provides four Form C digital outputs
and three Form A digital inputs. You can use a Form A digital input to monitor a
breaker to verify how many times the breaker trips. When the breaker has reached
its limit for the number of trips, you can use the digital output to light an LED next
to the breaker so field personnel are alerted. You can also use a Form C digital
output to send KYZ pulsing information to third-party system equipment.
All digital outputs can deliver a continuous signal or a pulse. (Contact
Power Measurement for complete information regarding relay applications.)
CAUTION
The relay outputs of the meter should never be used for primary protection functions. Be sure that you are
familiar with warnings at start of this document, as well as those presented your meter’s
Installation & Basic Setup Instructions .
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.
