<p>A control for an injection molding machine (10) is provided including: a processor module (110) producing set point signals in response to detection of coincidence of, selectably, analogue input signals, binary status signals, and elapsed time signals; and, a signal processing module (104) for periodically producing control signals in response to the set point signals, measured parameter signals and control algorithms relating set point values and measured parameter values. A DC output interface module (102) is provided including a plurality of DC output interface circuits for applying binary control signals to machine devices. The DC output interface circuits include self-latching over-current protection including means for sensing a latched condition thereof to produce an overcurrent fault indicating signal available to the processor module (110). The processor module (110) includes an expansion bus for connection of the signal processing module (104) and the DC output interface module (102).</p> |
