Prices starting at:
Call for Availability

1/4 DIN sized multiple-input controller for 4-20 mA signals from pH, ORP, conductivity, dissolved oxygen, or other liquid analytics, 4-20 mA signals from pressure, temperature, level, or flow process control. Comes standard with four analog and three frequency contact inputs, four relay outputs plus four analog outputs, further expandable with I/O options. NEMA 4X polycarbonate enclosure with large LCD display and Modbus TCP over Ethernet communications.

Get the functionality of a PLC, integrated HMI, and SCADA at the price of a transmitter and the size of a loop controller, for automated control on a budget.

The basic model Aquametrix AM-2300 controller accepts a total of four inputs from 4-20 mA output probes and three square wave inputs from pulse instruments, like paddlewheel or magnetic flowmeters. Four relay outputs are programmable from any of the inputs or by the difference of two analog inputs. The AM-2300 can be expanded up to 16 inputs (eight physical, eight virtual). More complex functions can be customized at the factory, and more I/O options are available by adding an expansion card.

The web-integrated 2300 controllerlets you view your controller's screen from any secure web browser after providing a security password, and can send e-mail or text notifications. You can even use a web-based setup wizard to configure the controller from a laptop PC, cell phone, or tablet. If you prefer, you can use the AM-2300 front panel for setup. The easy-to-navigate menu system provides full functionality.

Key applications include control for liquid analytical (pH, ORP, dissolved oxygen) or process (pressure, temperature, flow, level) instrumentation, small- to medium-sized manufacturing applications, and tank level monitoring.

  • Inputs for four 4-20 mA sensors of any kind in any combination: pH, ORP, conductivity, dissolved O2, chlorine; Ability to perform differential measurement from two analog inputs
  • Inputs for three frequency or pulse counters, including flow sensors
  • Totalizers for flow channels
  • Counter/accumulator for tracking equipment on time
  • Minimum of four programmable 5-amp relay outputs
  • Alarm notifications by e-mail, text, display, or all three for each input
  • Web enabled from setup to data collection to secure remote viewing with password protection and three levels of security
  • Modbus (server/slave) communications via TCP/IP
  • Log data to SD card, download .CSV files via web, FTP, or email
  • Front-panel display shows status, probe enable/disable/calibrate and system configurations
  • 1/4 DIN panel mounted enclosure, add NEMA 4X adapter for wall mounting
  • TUV and CE certification
