The PD420 4-20 mA current loop set point generator provides a convenient way to generate a 4-20 mA signal that can be used to control another device.
The PD420 features a backlit LCD display that can be programmed to display 0-100%, 4-20 mA or 3-21 mA and output either 4-20 mA or 3-21 mA.
A built- in dial is provided to vary the displayed / output value.
The dial may be programmed for coarse or fine adjustment.Features
