Dynisco ATC 770 Pressure Controller

ATC 770 Pressure Controller

DYNISCO MODEL ATC770 1/4 DIN Self-Tuning Pressure and Process Controller
Description The ATC770 pressure and process controller, with its unique self - tuning algorithm, makes it possible to set up a process such as extrusion, quickly,
easily, and with a minimum of operator adjustment. Inputs include 350 Ohm strain gage, DC voltage and DC current, making the ATC770 compatible
with a wide variety of process transmitters, and thus able to control a number of factory functions. It is fully configurable with a combination of jumpers
and menu options, as well as providing a selection of readout option.
