Demand-Signal Board with Four Signals & Five Ramps
The four demand-signal levels can be set on the Eurocard by continuously adjustable screw potentiometers and are called up via solid-state circuitry incorporating an optocoupler and FET switches. LEDs indicate which demand signals are switched-in. By soldering in the appropriate bridge connection for each demand-signal, the signal polarity can be set either positive, negative or made switchable via a polarity inverter switch. A ramp gradient can be set for each demand-signal on the Eurocard or externally. The fifth ramp (zero ramp) operates when all demand-signals are switched-out. The ramp function can be deactivated via an external signal. A 24vdc voltage signal is required to call up demand-signals via the optocoupler.
