DP1C Differential Pressure Controller
Specifications
The controller is originated from the DP10x11, with no transmitter output but with 2 relay outputs, LCD display and 3 keys for displaying and setting control parameters. Therefore, most of its technical parameters are the same as those of DP10x11. The different parts are:
Relay: 2×SPST, 3A/30VDC, 3A/250VAC
Display and Keys: large LCD with unit , backlight and 3 keys
Models
Measuring Ranges
1. Set the 5 engineering units by DIP switch and the related LCD indicator will be on.
2. For zero center models, add “Z” at the end of the model. For example, DP1**Z, means the range
is -30-0-30Pa. Only ranges 1~6 have this selection.
3. If the measured value is -0.XXX, it will be displayed as -.XXX on the LCD.
