The VT-SWMA Modules series is a group of analog command value modules designed to control hydraulic valves with integral electronics and to realize simple hydraulic functions through digital actuation.
These modules operate from a 24 VDC supply, mount on EN 60715 top hat rails, and use screw-type terminals for electrical connection in compact control installations. The control signal is generated from a differential command input, selectable preset command values, and an adjustable zero-point offset, with amplitude attenuation available for the input signal. The series also includes a ramp generator with five adjustable ramp times, four command value call-up options, polarity inversion, and 4-quadrant recognition so signal changes can be assigned to defined ramp behavior. Integrated LEDs, measuring sockets, and front-mounted potentiometers support setup and monitoring by giving direct access to power status, active command selection, polarity state, ramp activity, internal command value, and ramp time.
