Description
The Essex Engineering Model 2416 Manual Loading Station is a conservatively designed, reliable unit that provides a 4-20mADC isolated output which is directly proportional to a voltage or current input. Data conversion is very accurate, done via 12-bit A/D and D/A modules.
When in the AUTO mode, the output is directly proportional to the input, with the large upper digital display indicating the process variable and the small lower display indicating the percent output. Transfer from AUTO mode, the output is directly proportional to the input, with the large upper digital display indicating the process variable and the small lower display indicating the percent output. Transfer from AUTO to MANUAL is bumpless with no change in the output. The output can then be increased or decreased via the UP and DOWN pushbuttons. Transfer from MANUAL to AUTO utilizes a field settable ramp time, or the output may be manually changed to match the input, via pushbuttons.
The unit contains several field selectable variables such as ramp time from 0.2 to 134 seconds for a zero to one hundred percent output change and zero or non-zero reset on power up. Transferring between AUTO and MANUAL modes is accomplished via the AUTO/MANUAL pushbutton. Indicators are provided to display in which mode the controller is operating.
