Feature modules , with high connectivity capabilities and integrated features . It is available in a range that includes models for DIN rail mounting ( with or without LCD ) and panel mounting . Both models are available in three versions ( basic , enhanced and highend ), which differ in terms of connectivity and number of I / Os . The main benefits are :
• Built-in high-efficiency ExV , energy saving algorithms and smart device guide .
• Intuitive semi-graphic LCD with icons , languages customisable user interface and easy wiring .
• System interoperability with third-party devices via standard protocols ( Modbus , CAN and BACnet ).
• Cost savings through universal channels for I / O optimisation and fast programmability during production and maintenance .

Ivan Potter , CEO of i4 Group and iLED ( Pty ) Ltd . c . pCOe is the new I / O expansion card , built using a CARELproprietary microchip , that allows considerable flexibility in the configuration of the various pins , both as inputs ( support for passive NTC , PTC , PT1000 probes , digital inputs and active voltage and current probes ) and as outputs ( 0 – 10V , PWM ).
The c . pCOe card is available in two versions :
• bBasic version , with a total of 16 I / O channels available , 10 of which can be configured as analogue inputs or outputs , and six relays .
• eEnhanced version , same I / O configuration as the basic version , with the addition of a built-in driver for managing a CAREL unipolar electronic expansion valve .
C . SUITE - SOFTWARE DELVELOPMENT PACKAGE c . suite is the programming suite for the c . pCO family programmable controllers , designed as a set of interdependent modules for each stage of application development for HVAC / R units or systems . c . suite allows a group of professionals with different skills to work as a team on the same project , increasing the efficiency of each team member . The application program is developed as logically independent parts by different professionals , each of whom uses a different software tool . All these SW tools cooperate with each other by continuously exchanging data , and as an option can be managed by a software versioning control system ( SVN ).
To each their own tool : With c . strategy , the expert in thermodynamic algorithms can prepare the heart of the system ’ s operating logic . With c . mask , the developer can create the most suitable user interface : when the application program is ready , in c . design it can be transferred to any hardware configuration by configuring the controller type and size , I / O mapping , communication protocols , default parameters , data loggers and more . For OEMs , then , c . factory can be used to

programme the controllers on the production line , load the application program onto the controller as configured , while in the field the commissioner can use c . field to help set-up the system , with full access to parameters , alarms and real-time monitoring with graphs . c . suite provides a wide range of libraries with different functions from basic logic-arithmetic functions , to complex control algorithms for managing various devices , both CAREL and third-party .
Combining these elements with the AHU manufacturer ’ s know-how allows the application to be designed and developed to make every system your system . RACA
