ICP DAS TouchPAD features all in one functions such as: quick deployment, rapid integration, easy maintenance and display. It cut the cost of PLC and HMI yet provides similar or even more convenient features. By using ICP DAS TouchPAD (TPD) to control the devices and function as communication interface; TPD can work as a controller equipped with display function which add more values and upgrade the competitiveness in project implementation. SC-4104-W1 module provides three types of built-in control logic: each type provides three interlocking control functions. The user can freely switch in functions to quickly build and design most appropriate applications.
In most temperature control applications, usually it uses one master control panel to work with more than one control boxes. However the master control panel can only communicate with the control boxes connected under its architecture. Each time when adding new sensors or modules to the system for new requirement, it is required to design a new architecture. However, for TPD-283U, our driver allows to add new modules freely at any time, no matter via communication interfaces such as RS-485 serial communication device or Ethernet, which provides a friendly and easy solution to the maintenance staff.
This application is to implement lighting control system for sickrooms in a local hospital, we will transform traditional control system to smart building automation control system. The following devices are the major devices used in the applications:
The SC-4104-W1 is perfect to be used in Fan Coil Unit and indoor lighting control. It features built-in logic for quickly switch to different scenarios. A variety of scenarios interlocking reactions are provided for users to quickly switch to desired fan speed and lighting intensity.
Used for lighting controlling in the sickrooms and walkway.
TPD-283U is 2.8 inch HMI and designed for data acquisition of the modules. And it provides seamless integration with the software(InduSoft) for central control. Unlike traditional control panel, TPD-283U features more functions as below: 1. Built-in DCON/Modbus Protocol, which allows to communicate with the devices that is equipped with the same communication protocol; not like the general control panel which can only control a few devices. 2. More flexible built-in C/ladder language, it also can work as a Gateway for different devices. 3. Features one RS-485 serial communication interface and one Ethernet interface. In this application, it performs data acquisition from the lower modules and then transmits the data to the central monitoring software via the Ethernet.
The TPD-283U and SC-4104-W1 provide a wide range options for used in different applications, in addition to the interlocking control, more control functions are provided as below: 1. Cooling Control 2. Heating Control 3. Alarm Control In this application, the TPD replaces the previous controller and displayer, and the SC-4104-W1 is used to replace the lighting control and Fan Coil Unit. This cost-effective and easy-to-use solution provides competitiveness in project implementation.
