| Catalog HY14-3201/US Technical Information General Description w The ET104 series electronic module is used to control TDA and TEA proportional throttle valves configured with the `L' solenoid option. For valves configured with the `M' solenoid option, refer to driver card ET154. The module accepts a 0 to 10 volt command signal, and produces a proportionally linear output current used to drive the valve's proportional solenoid. Note that the linearity of the valve itself determines the linearity of the system. Refer to the specific valve data for actual linearity performance. Two ramp adjustments provide control of actuator acceleration and deceleration. w a D . w aS t ee h 4U t om .c Drivers Series ET104 A )( B Y Features * * * * Processing and amplification of the externally supplied positive set-values into output signals for the control solenoid. Can be combined with EZ150 or external programmable control. DIP switch from internal ramp generation to external ramp setting. MIN/MAX limiters for matching the working range to the full set value range. Pulsed low-loss amplifier power stage with supporting constant current control for constant, temperatureindependent, solenoid forces. Specifications F * * * Dither generator with applied frequency to improve static characteristics. Diagnosis by means of diagnostic sockets as well as LEDs for indicating working conditions.
