Product Description

Bosch Rexroth is a world-class designer and manufacturer of a wide range of motion control, automation, and general engineering components. Its products include hydraulic systems where advanced precise control is required. Their typical areas of application include plastics machines, machine tools, transfer lines, and presses.

The VT-VSPA2-1-1X-T1 is an electrical amplifier for controlling direct-operated proportional directional control valves without electrical position feedback. It supports four command values which can be adjusted using potentiometers and four command value call-ups. This control unit is equipped with LED indicator lamps that inform users about its operating status and aids in fault resolution. It has one ramp time and requires a nominal operating voltage of 24V DC with a tolerance between +40 % and –5 %. The amplifier’s current consumption is less than 2A, while its power consumption rating is less than 50 VA. It weighs 0.31kg and uses a 32-pin male connector in line with DIN 41612, form D.

Reverse polarity protection is available for voltage supply in the VT-VSPA2-1-1X-T1, ensuring that it is safe from damage when the power supply polarity is reversed. Its ramp time adjustment range is 30ms to 1 second, while its permissible operating temperature range is from 0^oC to 50°C. The circuit board of the amplifier is the Euro-card of 100m width and 160 mm height per DIN 41494. Its base material is synthetic resin bonded paper, and it has a high density. Thanks to its compact size, its handling and installation are simplified. It also displays a high level of durability, requiring low maintenance for its continued use. The appropriate storage temperature range for the electrical amplifier is –25 °C to +85 °C.
