Description Component series 1X Analog, Modular design For valves: (Z)DBE 6-1X DBE(M) 10-3X, DBE(M) 10-5X DBE(M) 20-3X, DBE(M) 20-5X ZDRE 10-1X Features Differential input for voltage Ramp generator with separately adjustable ramp times "up/down" Maximum current and 10% current adjustable Characteristic curve generator Clocked power output stage LED display of the solenoid control (brightness proportional to the solenoid current) Reverse polarity protection for the operating voltage Product description The amplifier modules are suitable for the control of a proportional solenoid. They are snapped onto top hat rails according to EN 60715. The electrical connection is established via screw terminals. The modules are operated at 24 V direct voltage. The solenoid current (actual value) is measured and compared to the externally provided command value. Any occurring differences between actual value and command value, e. g. caused by a change of the solenoid temperature or the operating voltage, are compensated. The activation of the solenoid control is indicated by LED “H3”; its brightness is proportional to the solenoid current. Using one trimming potentiometer each, the following can be set from the outside: a separate ramp time for upwards and downwards ramp (via R11, R12 → tmax approx. 5 s) the incline of the output characteristic curve (via R1, R2) Type code 01 Valve amplifier for proportional valves without electrical position feedback, Analog, Modular design For valves: (Z)DBE 6-1X DBE(M) 10-3X, DBE(M) 10-5X DBE(M) 20-3X, DBE(M) 20-5X ZDRE 10-1X 02 Component series 10 ... 19 (10 ... 19: unchanged installation and connection dimensions) 03 Further details in the plain text 01 02 03 VT 11131 ‒ 1X / * Technical data General Component series 1X Type of electronics Analog Design Modul Voltage supply Operating voltage Nominal U V 24 Lower limit value UB(t)min V 21 Upper limit value UB(t)max V 35 Power consumption max.
