Pulse Output
A Digital Output Relay allows connection to any Alarm, Control Alarm, Logic, Alarm Event,
Hold, Input or Output Fault, or Digital Input.

Invert Enable
Disable (default)
Inverts the input state of the applied digital input
such that inverse relay operation is achieved
Time proportional output is a form of a process variable transmitter or control output that
pulses the relay as a pulse width modulated signal that is proportional to the input signal over
a configured input range. The Time Proportional cycle time is configurable between 0.1 and
999 seconds while the duty cycle is directly proportional to the selected input signal.

PV Source
High Range -99999 to 99999
default = 100.00
The high range is the PV based engineering unit
value configured as the value that will produce a
100 percent (always active) duty cycle.
Low Range -99999 to 99999
default = 0.00
The low range is the PV based engineering unit
value configured as the value that will produce a
0 percent (always inactive) duty cycle.
Invert Enable
Disable (default)
Inverts the proportional range of the applied
analog input such that inverse relay operation is
achieved.
Cycle Time 0 to 999 seconds
default = 10
Cycle time is that time period, in seconds, the
relay will be activated.
Min Off Time 0 to 15
default = 0
Minimum off is that time period, in seconds, the
relay will be activated.
