# IP50DRA/IP50DRC INTELLPAK Gradient Response Computing Unit.

The INTELLPAK IP50DRA and IP50DRC are thin plug-in gradient response computing units that produce a DC signal output changing at a fixed gradient against an input DC signal. If the input signal changes at a rate higher than the preset gradient, the output signal changes at the set gradient, but the output follows the input if the change is slower than the preset gradient.
