Model 2300 - The multipple analog signal controller

The 2300 controller offers a real breakthrough in process control. It features the functionality of a PLC and a SCADA in a compact package for the price of a transmitter. The 2300 basic unit accepts a total of four inputs from 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: just contact us with your needs. More inputs or outputs are provided by purchase of an optional 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 includes a data logger that writes to an SD card which can also be downloaded from the web. 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 ¼ DIN enclosure. No other controller packs so much capability into one small package at a great price. For operators of small industrial or municipal systems that think SCADA means expensive, the 2300 may be the perfect fit to both your control and your budget.
Features
• Inputs for four 4-20mA sensors of any kind in any combination:
pH, ORP, conductivity, dissolved O2, Chlorine, and more.

• Outputs of four relays programmable for any of the inputs.

• Alarm notifications by e-mail, text, and/or display for each input.

• 100% web enabled from set-up to data collection to remote viewing with password protection

• Perform differential measurement from two analog inputs

• Data logging onto SD card and downloading from web

• 1/4 DIN panel mounted enclosure with adapter for wall mounting

• Three levels of security to allow the appropriate access to personnel

Multi parameter analyser / controller DAX
choice for flow, pH, ORP, or conductivity

The DAX is designed to be an extremely flexible, easy-to-use, multi-paramet er analyser/controller. Just select the parameter you want to measure from the LCD menu on the inside front cover. Choose from conductivity, pH, ORP, or  flow. The DAX gives you access to two displays. A bright LED numeric display with a bargraph on the outside front panel, and a two-line, 16-character LCD display on the inside. The LED readout can be seen from several yards away. The distinctive color-coded bar graph makes diagnosing pump and alarm malfunctions easy. It will immediately indicate if you are within the process parameters you’ve set (green), if the control relays are on (yellow), or if the process is in alarm conditions (red). All configuration and control functions are performed on the LCD menu inside the front panel.

You’ll also be able to perform calibration functions and check temperatures (where applicable) from the front panel LED. Since this routine maintenance doesn’t require opening the front panel to access the main menu on the side, configuration settings can’t be changed by mistake. You can perform process and temperature calibration from the LCD menu, where calibration slope, temperature, and efficiency are displayed.

DAX controller/analysers provide control of external devices using two independent control relays. A third relay is preset to act as an alarm, but can also be used as a process control relay. It has both high and low ON setpoints, with adjustable OFF setpoints.

Factory-set for bidirectional control, both control relays can be set for either rising or falling process with easily programmed On and OFF setpoints. Each control relay has a built-in independent cycle timer, with field-set ON and OFF times. This feature enables tighter control of batch processes by eliminating chemical overshoot.

The DAX is packaged in a rugged NEMA 4X polycarbonate enclosure, making it ideally suited for heavy-duty applications, such as industrial wastewater neutralization, municipal water and wastewater, pulp and paper,and process control.

Each DAX comes complete. There are no extra costs associated with buying boards for different applications, or buying components to achieve NEMA 4X ratings. A universal mounting kit is included with each unit for surface panel and pipe mounting.
