Product description
The MultiChannel-Series are powerful and versatile compact-multichannel-controllers with a capability to record data, if the recording function is requested and activated. Thanks to that it is one of the first industrial devices which integrates advanced control functions (PID, ON/OFF, time & profiles etc.) and logging of set points, excitations and current state of controlled objects. Based on Linux firmware, is stable and the touch screen makes configuration easy and comfortable and data presentation also readable and attractive. Although the MultiChannel-Series are built in a quite small housing, it can integrate up to 48 inputs, and its construction allows user almost free configuration by choosing up to 3 from 27 available input/output modules.
Functionality
Signal measurement
Signal measurement is the essential function of the device. This compact appliance, depending on the needs, can be equipped with dedicated modules for the measurement of signals from detectors with a current output (mA), voltage output (in mV and V), from temperature measurement detectors (by thermocouples and RTD elements) or modules with universal inputs that can measure almost any type of signal.
MultiChannel modules of progressive-reverse counters, tachometers and flow meters and multi-input modules of digital inputs which can read a state of the button and allow for a binary data input has been developed to process digital signals.
Mathematical functions
Mathematical functions allow the measurement results to be operated freely. MultiChannel allow you not only to use arithmetic and trigonometric functions such as addition, multiplication, sine, raising to a power, but also logical ones (comparing to a constant, comparing the measured values or multiplexer) which makes the developing of the advanced applications much more easy.
Process control
Process control is a natural consequence of the availability of the aforementioned mechanisms. MultiChannel, however, has many more control capabilities hidden within itself than simply standard relay outputs switching. PID control is the basis of modern automation systems and in this device every of 60 (or 90) measurement channels available can be set as an independent PID controller. What is more, a setpoint for this control process does not have to be a constant value set by the user.
Timing profiles
Software built-in timing profiles (free programmable runs) allow for the unique freedom in shaping a run control and possibility to start the control process at a preset time or when a defined event occurs. Their functions enable the control to be stopped at a specific time/conditionally at any point of the run, to be looped and it is possible to carry any other operation on a setpoint. The results of the control must have an outflow point in a physical element that controls the object, and therefore the manufacturer has prepared many modules which can be used for it – diverse relay outputs, multichannel SSR electrical relay drivers and current outputs with full galvanic insulation against other I/O.
Various methods of data presentation
Various methods of data presentation are other advantages of the device. The user can choose between 8 data display modes – from standard digitally read indicators, through indicating instruments, vertical and horizontal bargraphs and charts (typical of brush recorders), to phasor diagrams usually seen in devices used in power industry – and all of it is available from a touch pad screen that allows for a swift switching between displayed data and between modes of presentation.
Data recording
Data recording makes a kind of a value added to the tremendous possibilities shown above. MultiChannel can record any 60 measurement channels at a speed of 10 samples per second. It has 1.5 GB built-in flash memory, intended for data registration, which, in the case of 24 measurement channels every second, is enough for about 2 months of continuous operation. The function of data registration has been also optimized for the use of hardware resources of this device - the channels for registration are grouped (1-6 channels) and in each group a speed of registration can be freely set. Additionally, there is a unique option of alternative (higher or lower) speed registration, which is set off only under user-specified conditions. This solution allows you to precisely trace the object parameters in critical situations.
Communication with the environment
Almost every modern electronic measuring instrument is equipped with some type of a communication interface - MultiChannel has several of them. The primary type of an interface is USB Host. It allows you to connect the device not only with a standard mouse and keyboard, but also an external hard drive (e.g. flash) and to download registered data. More interesting, from the point of view of the communication with the environment, is RS-485 interface with Modbus RTU Protocol available in standard equipment. Like other interfaces, RS-485 and RS-232 available in an optional interface module, interface device, each of which can operate independently as Master or Slave at a different transmission speed. Thus, the use of MultiChannel does not have to be limited to the presentation of measured data read from built-in modules and to the control of built-in outputs. Enhanced menu interface allows you to easily configure it, so that MultiChannel will read data from any device equipped with Modbus RTU, and will control a condition of outputs in it, if it can be remotely controlled.
Ethernet Interface
However Ethernet interface gives the greatest possibilities. Built-in Web servers, as well as Modbus TCP Protocol give user the possibility to use predefined data visualizations based on Java applications. If a dedicated process visualization is required, the presented mechanisms can be easily adopted to the individual needs of the customer. Basing on freeware tools for website building available on Web, almost everyone is able to prepare, within few minutes, their own visualizing application, which can be launched almost on every computer connected to the Internet.
