ABSTRACT:
An H-5 relay air valve emulating circuit for use in an electropneumatic railway brake control equipment including an operational amplifier comparator and a solenoid relay. The operational amplifier comparator includes a positive and a negative input and an output. The positive input is connected to an automatic brake cylinder request terminal, while the negative input is connected to a reference signal terminal. The output of the operational amplifier comparator is connected to the electrical coil of the solenoid relay which has a movable heel contact as well as a front and a back contact. The front contact is connected to an independent brake cylinder request terminal, while the back contact is connected to a zero reference terminal. The movable heel contact of the solenoid relay is connected to an independent contact point of a J-relay emulating circuit which is conditioned to either produce 160% of the simulated control pressure signal or to produce 100% of the simulated control pressure signal.
