The PD420/21 set point generator provides a convenient way to generate a 4-20 mA signal that can be used to control another device.
Both feature a backlit LCD. The PD420/21 set point generator 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.
The signal generator is available as a panel mount or NEMA 4X version. In addition, NEMA 4X enclosures are provided to house up to three of the panel mount versions.
Decals are provided for %, mA, Open, and Closed for the user to apply to the faceplate. There is also a decal with a white background for the user to write a custom label.
