Product Description

Bosch Rexroth’s hydraulic systems and their components are designed with advanced state-of-the-art technology. These highly functional units have several applications, including plastics machines, machine tools, transfer lines, and presses. The VSPA2 electric amplifiers by the company are hydraulic control units with two output stages.

The VT-VSPA2-1-1X-T1-003 is a model of Bosch Rexroth’s electrical amplifiers used for various applications in hydraulics. It is specifically designed to control direct-operated proportional directional control valves without electrical position feedback and does this with a nominal operating voltage of 24V DC. This voltage rating has an allowance between –5 % and +40 %. The amplifier also has a power consumption rating of less than 50 VA and current consumption of less than 2A. It has one adjustable ramp time with an adjustment range of 30ms to 1 second. Additionally, it has four command values which can be adjusted with potentiometers and four command value call-ups.

A 32-pin male connector per DIN 41612, form D is the type of connector present in the VT-VSPA2-1-1X-T1-003. The amplifier card is designed as a 100m high and 160mm long printed circuit board in the europe format. Its suitable card holders are the closed card holder VT12302 and the open card holder VT3002-1-2X/48. It is also suitable for installation in a rack. The reverse polarity protection feature of this device’s voltage supply protects it from being damaged when the polarity of the power supply is reversed. It is equipped with LED indicator lamps to detect its various operating states and promote simplified fault identification and resolution. This electrical amplifier should be stored at a maximum temperature of 85 °C and operated at a maximum of 50°C.
