Essential Info

Connecting and controlling home, office and industrial equipment by application servers or web browsers can be costly and challenging. The CAi Networks WebControl Universal Industrial Controller is an innovative, flexible, and affordable solution that extends the capabilities of computer servers. This is accomplished by allowing integration with a network gateway and a router to form a patent pending smart grid technology.

Harnessing the power and openness of Internet web technology, WebControl uses W3C standard-based client/server communication methods to bring remote monitoring and control of equipment to any web browser -- anywhere, anytime, and with unsurpassed convenience and flexibility -- or to a web server, which can use GET/WGET to read status of input and output of other equipment through WebControl, so monitoring and control can be achieved through web-based applications.

WebControl offers a powerful set of capabilities including simultaneous monitoring of digital and analog sensor signals, temperature, and humidity sensors, and Transistor-Transistor Logic (TTL) output status through a programmable Boolean Run Engine (BRE).

Simply connect WebControl to an appropriate power source, the LAN, and the desired equipment, and remote monitoring and control is just a mouse-click away.

What's Included

  • 1x - CAi Networks WebControl Universal Industrial Controller
  • More Info

    Inputs Support
    WebControl can simultaneously connect to 8 digital inputs, 3x10 bits A/D analog inputs provides 1024 steps accuracy, 8 optional DS1820/DS1822 based digital temperature sensors, and 1 optional Honeywell HIH-4000 Series humidity sensor. WebControl also has 20 built-in timers based on NTP or on board crystal to maintain accurate time events. All these inputs can be used to feed to the Boolean Run Engine for decision making. Those information also can be rendered to clients on the remote sites through browser and can also be made available to server-based applications running on a web server.

    Flexible Output
    The eight TTL output is by default at logic zero. When an output is triggered or turned on, it sends out 5V, maximum drive current 20MA per output. It is capable to drive an optical isolated SSR (Solid State Relay, normal input control voltage 3-32V current is < 10mA) device to run a motor, siren, light, heater, refrigerator, or other desired component.

    WebControl allows user to control each output through browser from thousands miles away, or though its built-in BRE(Boolean Run Engine)automatically, or through the WGET protocol from application servers.

    Supplicated Control
    WebControl's BRE (Boolean Run Engine) allows AND, OR, delay, or momentary on for each output based on all the I/O condition. There is no learning curve, simply use browser and keyboard to enter the I/O needed for the control logic. It has delay function allow 0 to 6335 seconds delay for ON or OFF in the BRE. The momentary ON function has resolution of 0.1 to 100 second(s).

    WebControl PLC has a true PLC firmware. The PLC firmware allows user to write assembly like PLC code to compare inputs, define timer or delays, determine when to send email notifications. Users can write up to 4000 lines of PLC code. There are real examples in the PLC User Guide for reference. User needs to decide if the WebControl purchased loaded with PLC firmware or BRE firmware.

    Simple to Install and Manage
    WebControl resides as a well-behaved 10BaseT-interfaced device on the local network, and has a built-in DHCP client to automate network configuration that can be defeated to assign a fixed IP address via WebControl's browser-based interface. WebControl's host name can be set as desired for installations with multiple WebControl units, and local time zone to reflect the location.

    WebControl has an embedded web server to facilitate its browser-based interface, and built-in SMTP, and NTP time servers facilitate outbound email notifications, and time synchronization. WebControl provides authenticated access, and security can be enhanced by allowing network access to WebControl from only authorized IP address ranges.

    Automatic Notifications
    WebControl is capable of automatically sending email notifications to a specified user, a mailing list, or a cell phone when the state changes on any of its eight outputs. With this notification feature, advice can be sent automatically, for example, when the temperature exceeds 90 degrees and the air conditioner is turned off, when humidity has reached 90% and a humidifier is turned on, or when a secure area has been breached and a siren is activated.

    Energy Efficient Device
    WebControl requires 9V DC power source not to exceed 12VDC (9VDC is recommended) power source. With no load, it consumes 170MA. (< 2 watts. When driving power load, the load driven current is in addition to the WebControl CPU.)

    Edison -- santa rosa, California   11/7/2012
    Great little board with many funcitons. Programming is easy and powerful. Manufacture also offer direct help and firmware updates.
    AL -- webster, MA   9/23/2012
    First unit failed. SH replaced promptly. Locic programming worked great. Wasn't able to get 1-wire temp sensors to function reliably even after many wiring changes. Returned product and upgraded to a much more expensive Elk controller.
    AL Huefner -- webster, Ma.   8/14/2012
    I purchased this product to provide web access and email notification of several conditions including: Heating Oil Supply Low, Backup Generator StatusON/Off and Fault Notifications, House Heating Failure, Close garage doors after 10 minutes if left open. I mounted it in my wiring center panel and it is powered by the common power supply in that panel. I am still in the process of implementing it but it is proving to be quite capable. The documentation is weak which increases the learning curve, but the unit was easy to install and came up immediately on my network. It is also easy to program, and very flexible. I expected it to be less capable then it is proving to be.
