At the SPS/IPC/DRIVES 2003 exhibition, PMA Prozeß- und Maschinen-Automation, Kassel, introduced
a new range of high-quality, rail-mounted devices: the PMA rail line. Designed for top-hat DIN
rail mounting, the units feature a particularly compact housing only 22,5 mm wide. Field connections
are made by means of removable terminal strips.
Thanks to their comprehensive and stand-alone functionality, PMA's distributed rail line units relieve PLCs and IPCs reliably from precise analog and fast signal processing tasks. Compared with conventional methods, the installation and wiring costs for PMA's rail line modules are significantly reduced. Another contribution from PMA towards intelligent, cost-saving solutions for distributed automation. Shared features of all rail line units Simple and convenient 3-key operation, and the multi-line LC display provide the operator with comprehensive local access to the process. PC-based configuration is particularly easy via the BluePort® front interface and the BlueControl® Oprogramowanie package. Another highly useful feature is the additional RS 485 interface in the mounting rail, with direct bus connection to the other rail line units (Modbus RTU protocol). Field couplers are available for the established field bus systems such as PROFIBUS, CAN, Ethernet, etc., thus permitting cost-effective linking of rail line equipment to PLCs, IPCs, and operating terminals. Apart from the new universal UNIFLEX CI 45 transmitter and the universal KS 45 controller, the TB 45 rail line temperature limiter comes in the same compact housing and with the same top-quality technical design. UNIFLEX CI 45 rail line The first units to be presented from the range are the UNIFLEX CI 45 rail line transmitters for universal application. The high-resolution (>15 bits) and fast scanning (100 ms) universal input permits the direct connection of temperature (TC, RTD), resistance, current, and voltage (V, mV - also high-impedance) signals. Furthermore, a second universal input as well as direct connection options for O2 sensors, frequencies, and counter functions are available. Two alarm relays can be used in parallel with the galvanically isolated, high-res U/I analog output. Universal controller KS 45 The KS 45 is ideally suited for all thermal control tasks that can be handled with switching outputs: 2-point, 3-point, or 3-point stepping. For this, the unit comes with two relay outputs (optionally as optocoupler outputs). With the help of the additional analog universal output, the KS 45 can even be operated as a continuous controller! Due to the fast control algorithm (100 ms), it is also possible to handle very fast heating processes. Moreover, the 2nd analog input permits continuous monitoring, e.g. of heating current, or it can be used as an external setpoint input. Alternatively, the 2nd input is available as a universal input, e.g. for additional signal linking or for oxygen measurements. The integrated maintenance manager provides warning when an actuator has reached a predefined number of operating hours, or if an input needs recalibration! An error list stores all generated fault messages. Because numerous additional functions, such as auto/manual switchover, timer program, programmer, and sensor monitoring, are standard in the new controllers, the installation time is reduced. What's more, you don't have to provide supplementary operating or monitoring equipment, and tasks that were previously handled by a PLC are now carried out by the controller itself - lower investment costs plus considerably reduced outlay for installation and wiring. PMA's novel universal KS 45 controller offers many features that were previously provided only in more complex units, or are completely new for this equipment class. Noteworthy is PMA's typical BluePort® front interface for direct connection to a PC or laptop. With the help of PMA's BlueControl® Engineering Tool, configuration and parameter setting of the universal KS 45 controllers are particularly easy, in addition to process value display and graphical trend recording. PMA will be exhibiting the new rail line family at the Hanover Fair/INTERKAMA 2004 in Hall 9, Stand F27. Detailed data sheets and colour flyers are available on request for the KS 45 rail line controller and the UNIFLEX CI 45 transmitter. The pictures show rail line modules as individual units and combined in a system. |
