Intuition-9 Series Multi-System Controllers - 24 Input - 12 Output

The Walchem Intuition-9 Series is a wall-mount water treatment controller for control of chemical metering pumps and valves in a broad range of water treatment applications. Four I/O slots allow complete flexibility in adding sensors, analog outputs and Linear Polarization Resistance (LPR) corrosion sensors, and a universal sensor input provides extraordinary flexibility so the same controller can be used with almost any type of sensor needed. Three to twelve relay control outputs allow the controller to be used in more applications.

Key Benefits

• Email alarm messages, datalogs, graphs, or system summary reports
• Datalogging
• Ethernet or WiFi for remote access via the Internet, LAN, or optional BACnet or Modbus/TCP
• Large, full-color touchscreen display with icon based programming makes setup easy
• Universal sensor input provides extraordinary flexibility; the same controller can be used with almost any type of sensor needed
• Four I/O slots allow complete flexibility in adding sensors, analog outputs and Linear Polarization Resistance (LPR) corrosion sensors
• Multiple language support allows simple setup
• Three to twelve relay control outputs allow the controller to be used in more applications
• Sixteen virtual inputs and sixteen virtual outputs
• Economical wall-mount package for easy installation
• On-screen and web page graphing of sensor values and control output status
• Complete flexibility in the function of each relay

I/O Modules

• Dual sensor input modules accept two sensors per module: contacting conductivity, electrodeless conductivity, pH, ORP, any Walchem disinfection sensor, or a generic sensor (Ion Selective Electrodes or any type of sensor with a linear voltage output between -2 VDC and 2 VDC).
• Three analog (4-20 mA) input modules with two, four or six input circuits are available for use with 2, 3 or 4-wire transmitters.
• Two modules feature two or four isolated analog outputs that may retransmit sensor input signals to a chart recorder, datalogger, PLC or other device, or connect to valves, actuators or metering pumps for linear proportional control or PID control.
• Another module provides two corrosion sensor inputs.
• Relays are available in several combinations of powered relays, dry contact relays, and pulse solid state opto relays.
• Auxiliary DC power option boards, available with either 12 or 24 VDC, may be added to support high-wattage transmitters or ancillary devices such as cell modems by supplying up to 10 watts of power.

Communications and Data

• The standard Ethernet feature provides remote access to the controller's programming via a PC connected directly, via a local area network, or via Walchem's Fluent account management server, and allows emailing of datalog files (CSV) and alarms to up to eight email addresses.
• The Modbus TCP and BACnet remote communications options allow communication with PC-based applications, HMI/SCADA programs, Building Energy Management systems, Distributed Control Systems (DCS), as well as stand-alone HMI devices.
• Two optional WiFi cards are available, one which allows simultaneous Ethernet and WiFi communications, and one that increases security by disabling Ethernet when WiFi is enabled.
• USB features provide software upgrade, saving all set points to a USB flash disk for import into another controller, and saving sensor readings and relay activation events to a USB flash disk.
