AP4830

DC Programmable Up / Down Ramp Generator

Unspecified 

APPLICATION

Model AP4830 is useful in controlling

process equipment requiring voltage or

current ramp control. Typical applica-

tions include temperature cycling, PID

controller setpoint control, motor con-

trol and bumpless control transfer.

OPTIONS

CS Canadian Standards Association

Certification.

U Urethane coating of internal cir-

cuitry for protection from corro-

sive atmospheres

CALIBRATION

Top-accessed screwdriver adjustments

provide typical ±3% zero and span

adjustability. Calibration is referred to

input in that adjustments are to correct

for input/sensor variations. Zero is

adjusted for the specified minimum out-

put with the input at the desired mini-

mum. Span is adjusted for the specified

maximum output with the input at the

desired maximum. Repeat adjustments

for maximum accuracy.
