Relay 1	Frequency proportional output is a form of a process variable transmitter or control output
Relay 2	that pulses the relay as a pulse rate that is proportional to the input signal over a configured
Relay 3	relay range. The maximum frequency is set by the cycle time that is configurable between
Relay 4	0.1 and 999 seconds. The pulse duration is fixed and configured in seconds by an on time
Frequency	parameter.

		See Table 6-3
Output Relay
	High Range	-99999 to 99999	The high range is the PV based engineering unit
		default = 100.00	value configured as the value that will produce a
			100 percent (Maximum Frequency) duty cycle.
	Low Range	-99999 to 99999	The low range is the PV based engineering unit
		default = 0.00	value configured as the value that will produce a
			0 percent (always inactive) duty cycle.
	Invert	Enable		Inverts the proportional range of the applied
		Disable (default)		analog input such that inverse relay operation is
				achieved.
	Cycle Time	0 to 999	Sets the Cycle Time of the maximum output
		default = 10	frequency.
			Max Freq=1/Cycle Time
			Freq Output = Max Freq * (% Input/100)
			For example:
			Freq Output (100%)=Max Freq * 1
			Freq Ouput (50%)= Max Freq * .5
			Freq Ouput (25%)=Max Freq * .25
	On Time	0.0 to 999		Sets the pulse duration. This value should be
		default = 5		less than the cycle time for proper operation.
				Typically this value is used to control the pulse
				duration for the finial output control element.
