Water and wastewater facilities have many process loops where a bank of displays or panel meters are needed for installation in control rooms or in remote cabinets.
When a panel meter display is required, consider the Nema 4X UL approved 330R2 1/8 DIN Process & Temperature Meter and Alarm. The 330R2 has a large 4 digit bright LED display and accepts T/Cs, RTDs, mA, and V inputs. The unit accepts two types of input power ranges: Low Level ACDC 12-24VAC/12-36VDC; or High Level ACDC 85-265VAC/90-265VDC .and can be field-programmed via the front push buttons or is PC-Programmable with free software. The 330R2 comes standard with two SPDT alarms and has an isolated analog output that can be ordered as an option. The High Level ACDC powered units include a –TX (Transmitter Excitation) option to power a connected transmitter. In addition, the display has an adjustable intensity setting which is especially useful when installed in direct sunlight.
The 330R2 can also be used as a low-cost pump controller when combined with a continuous-level transmitter. This allows it to be utilized for one of the most common pump control applications, controlling and alternating two pumps.
Key Attributes:
- Push button or PC-Programmable
- Nema 4X and UV resistant, bright 4-digit LED display with adjustable intensity setting
- Two SPDT alarm contacts included as standard
