Product Description:
Bosch Rexroth Indramat manufactured the VT-5003-42/R1E. The Bosch Rexroth Indramat VT-5003-42/R1E IO card operates comfortably within a pretty broad input voltage range of -10% to +40% around its sweet spot of 24 VDC. That means you can safely run it anywhere between 21.6 and 33.6 volts. That's a big difference from the erratic voltage swings you often see in industrial settings. Where you might have big motors turning on and off or less-than-stellar supply conditions from your upstream electrical infrastructure—those intermittent loads can cause voltage changes. The card's internal electronics stay stable, you avoid electrical overstress, and the risk of brownouts decreases by operating within that voltage range.
Where you can't always remove voltage transients at their source, this wide tolerance helps you build more robust automation methods into your system design. The VT-5003-42/R1E draws about 0.6 amps under normal conditions. But under full load or when there are transients that can spike up to 1.25 amps for a short time, that's something you need to factor in when dimensioning your power infrastructure. And when choosing circuit protection devices—like fuses or thermal-magnetic circuit breakers—you need to consider that power supply profile too. If you don't, you might get annoying tripping, heat buildup in your wires or connections, or even catastrophic failure. That's not what you want. One of the card's main jobs is signal interfacing, particularly with pressure control systems.
The voltage-based analog command input for pressure translates linearly from 0 to 10 volts to a pressure control signal between 0 and 100%. That input has an impedance of more than 50 kΩ, so it won't load down the driving signal source. That's crucial for keeping the shape of your analog control signals intact from automation controllers like PLCs. The analog feedback input (pist) can receive signals in either of two modes: as a 0 to 20 mA current loop or as a 0 to 10 V voltage signal. By enabling dual-mode reception, you get a lot more capability out of the card. In the latter mode, a precision resistor (usually two kΩ) transforms the current into a voltage that's ready for internal analog-to-digital conversion. Like the command input, that feedback channel has a high impedance threshold of more than 50 kΩ. That means the electrical properties of the receiving circuit won't impact the transducer or sensor supplying the signal.
