Pulsed Time Proportioning Output: Select
1 P u L
to
7 P u L
.
1 P u L
=
Linear and
7 P u L
= most nonlinear. Changes output linearity for
use in cooling applications or for extremely fast response
processes. At the center of the proportional band, a pulse value
of 1 provides an output of one second on and one second off
(50% output). A pulse value of 2 provides an output of one
second on and two seconds off (33% output). Output at center
of band equals one second on, 2
(pulse value-1)
seconds off.
