VT-5003-42/R1E by Bosch Rexroth Indramat

The VT-5003-42/R1E from Bosch Rexroth Indramat is a precision IO card in the VT-5000 IO Cards series designed for robust industrial automation environments. This module operates on a 24 V DC supply, accommodating a generous supply voltage range of 21.633.6 V DC to ensure stable performance in the face of upstream voltage transients. With a nominal current consumption of 0.6 A and a maximum current consumption of 1.25 A, the card strikes an optimal balance between low-power operation and the capacity to handle short-term load spikes. Housed in a compact form factor weighing just 0.15 kg, the VT-5003-42/R1E features a 32-pin male DIN 41612 connector, form D, simplifying integration into standard rack systems. Its operational temperature span of 0 °C to 50 °C makes it suitable for a wide range of factory floor applications.

Technical performance of the VT-5003-42/R1E is highlighted by its dual-channel analog capabilities. The analog command input (pressure psoll) voltage range of 010 V pairs with an input impedance exceeding 50 kA, ensuring minimal loading on the driving PLC or controller. On the feedback side, the analog actual input (pressure pist) supports both 020 mA current loops (via a 2 k precision resistor) and 010 V voltage signals, each with an impedance above 50 kA. This flexibility allows seamless interfacing with a variety of pressure transducers and sensors. Electrical resilience is further reinforced by the card’s tolerance of B140% on its DC supply and its ability to tolerate up to 1.25 A peak draw without performance degradation. The choice of a 32-pin multi-point connector ensures reliable signal integrity across all channels in high-vibration industrial settings.

Operationally, the VT-5003-42/R1E delivers precise pressure control and monitoring. Its linear translation from a 010 V command to a 0100% pressure output guarantees predictable system behavior, while the high input impedance preserves the fidelity of analog waveforms. By supporting both voltage and current feedback modes, the module enhances diagnostic capabilities and reduces the need for external signal conditioning. Its tolerance for fluctuating supply voltages minimizes brownout risks and protects downstream electronics from damage caused by transient spikes. Maintenance downtime is reduced thanks to the card’s self-contained design and its compatibility with standard DIN rail or rack-mounted enclosures.

Integration of the VT-5003-42/R1E into existing automation architectures is straightforward. The standardized DIN 41612, form D connector facilitates quick replacement and hot-swappable maintenance in modular control cabinets. Engineers can deploy this IO card alongside other VT-5000 series modules to build scalable, multi-channel pressure control systems. Its industrial-grade construction and wide operating temperature range make it ideal for hydraulic power units, process control skids, and mobile machinery applications requiring reliable analog interfacing under harsh conditions.
