I/O Operations

The power monitor is equipped with two relay outputs and two status
inputs designed to provide a discrete interface with your application.

Relay and KYZ Output
Operations

The Relay output is an electromechanical Form C relay with contacts
rated at 10 amperes at 240V ac or 250V dc. This set of contacts is also
rated to meet IEEE C37.90 requirements for power circuit breaker
tripping duty. The KYZ output is a solid-state relay rated at 80 mA at
240V ac or 250V dc that provides higher reliability and long life for
low-power signaling duty such as a kWh pulse output.

The two outputs operate independently and you may configure each
output

s operation individually. You may use the display module or

communication to set the output configuration parameters in the
Advanced Device Configuration table. The output configuration
options for the relay and KYZ outputs include the following:

Control source: specifies what controls the selected output.
Options are 0= none; 1 through 6= pulsed output; 7= setpoint
control; 8 discrete I/O control. Default = 7

Output scale: specifies the scaling factor for pulsed operation.
Range 1…30,000; default = 10

Output width: specifies the pulse width for pulsed operation.
Range 0 or 40…2,000 ms

Force command: overrides setpoint, communication, discrete or
pulsed control until the force is released. Options are: 0 = no
change; 1 = force the output energized; 2 = forced the output
de-energized; 3 = release the force

Default output state on communication loss: specifies response
to a loss of communication. Options are 0= last state/ resume;
1= last state/ freeze; 2= de-energize/ resume; 3= de-energize/
freeze. See below.
