A custom 20-breakpoint linearizer. Custom linearizers can be applied to any analog input by
selecting them as the linearizer type for that input – see page 32.
The engineering range and units of the input source are assigned to the
custom linearizer output.
Selects the input source to be linearized – see Appendix A, page 79 for description of
sources.
Selects the breakpoint to be configured.
X is input to the linearizer expressed as a % of the electrical range.
Y is output expressed as a % of the engineering range.
2 Delay timers are provided. The delay timer is triggered by the rising edge of its assigned
source. An internal timer is started and, when the timer reaches the set Delay Time, its
output goes high for the On Time that is configured. After the delay time is triggered it
ignores any further transitions of the source input until the end of this delay timer cycle (until
the end of the On Time).
The source signal used to trigger the delay timer. Trigger
occurs on rising edge of the signal – see Appendix A, page 79
for description of sources.
The delay (in seconds) between the trigger received and the output of the delay timer going
high.
The length of time in seconds the delay timer output is held in the high state.
