The AquaMetrix 2300 Input Controller offers a breakthrough in process control. It features the functionality of a PLC anda SCADA in a compact package for the price of a transmitter. The 2300 basic unit accepts a total of four inputs form direct 4-20 mA output probes and three square wave inputs from pulse instruments such as paddle wheel or magnetic flow meters. Four relay outputs are programmable from any of the seven inputs or via the difference of two analog inputs. More complex functions between inputs can be customized at the factory. More inputs or outputs are provided by adding optional expansion card.

The 2300 is fully web integrated. The web-based set-up wizard makes it easy and convenient to set up and configure from the convenience of a laptop, tablet or cell phone. E-mail or text notifications are a snap, and the unit status can be viewed from any browser after providing a password. If you want to use the 2300 itself for setup, the easily navigated menu system provides for full functionality in a common sense approach.

The 2300 provides a low-cost solution to solve your control problems. It includes a data logger that can store as much data as can be fit onto the internal SD card. An optional card enables Modbus/RTU over RS-485 or Modbus/TCP communication directly to a computer or system. All of this fits into a 1/4 DIN enclosure. No other controller packs so much capability into one small package.

Applications for the 2300 Input Controller include:

  • Process control
  • Analytical (pH, ORP, DO, etc) or process (temperature, pressure, flow, etc) instrumentation
  • Small to medium sized manufacturers
