General:
KFM 903 is an industrial microcomputer-based controller series in control panel format 96 x 96 mm
with a performance range of up to 9 relay outputs (changeover), various signal inputs and outputs
as well as numerous possible optional extras. Communication with control systems is also possible.
Additional contacts can be switched time dependent using the integrated real time clock.
Controllers of the series 903 can be delivered with the type extension K in a freely programmable
version and then available functional packages can be added arbitrary within the hardware, using a
graphical workspace, so that a separate control system is often not necessary.
The belonging module software 99pkm provides beside ready to use controller modules a large
number of control functions and logical operations compact within the individual device, furthermore
expansion modules, an external malfunction alarm unit or a second freely programmable
controller 903K can be added to it by using the standard interface.
Alternatively, the delivery can be done unprogrammed with hardware in various types. In this case
the programming is provided by the customer or at extra cost by the factory.
The transmissive colour TFT indication is easy to read in both light and dark environments.
Parameter set, TFT- configuration, data logger recordings and fault history can be transferred by
means of conventional USB stick. Irrespective from that, the continuous logger data is automatically
saved on a regular basis if the USB stick is inserted.
The touch operation of the TFT- display is optionally available.
Depending on version, the industrial controller can configured and read out via USB stick.
