VT 5041-23/3-0D

Product Description:

Bosch Rexroth Indramat manufactures the VT 5041-23/3-0D. With a nominal voltage of 24 V DC in the middle, the Bosch Rexroth Indramat VT 5041-23/3-0D IO card works in a voltage range of 21.6 V to 33.6 V DC. With a tolerance of +40%/-10%, this is quite broad. Reliability in this range ensures the card and prevents operational disturbances caused by power supply changes. This is achieved electronically by using a strong voltage regulation circuitry, which keeps the internal working voltage constant regardless of input fluctuations. The exact signal processing needed for precise control depends on this regulation. The maximum current consumption of the card is 1.25 A, rated up to 0.6 A. This determines the power supply of the system. A higher current consumption means a higher power demand, which must be fulfilled. The quantity and type of connected input/output devices have a direct impact on current consumption. The card switches and controls the current with semiconductor devices like integrated circuits and transistors.

According to DIN 41494, the physical dimensions of the VT 5041-23/3-0D (100 x 160 mm) are in the Euro-card format. This standardization makes it easier to integrate and replace and guarantees mechanical compatibility with industry-standard racking solutions. For physical integration into control cabinets, the front plate dimensions (3 HE (128.4 mm) and 5 TE or 7 TE, depending on the variant) are also important. The total system weight and mechanical stability are influenced by the weight of the card, which is 0.19 kg to 0.21 kg, depending on whether a display is included. The card controls several analog commands and feedback data like valve position, swivel angle and pressure. 0…10 V signals, which correspond to 0% to 100% of the target value, are used for the pressure command (psoll), and actual pressure (pist) values.

The 2 kΩ input impedance ensures signal integrity and puts little stress on the signal source. With 2 kΩ input impedance, the swivel angle (swsoll, swist) and valve position (xVsoll, xVist) values are represented as ±10 V signals or ±100% of the target value. In hydraulic and pneumatic systems where these values have a direct impact on the system performance, precise signal representation is crucial for precise control. An Analog Digital Converter (ADC) on the card converts analog signals to digital signals, and a Digital Analog Converter (DAC) does the same. The card’s reliability in the industrial environment depends on its working temperature range of 0 °C to +50 °C. The normal temperature fluctuations in control cabinets and production environment are within this range. Thermal management factors like component layout and selection are taken into account in the card design to ensure steady performance within this temperature range.
