Product Description:

The VT 5041-24/3-0V is a plug-in input/output card produced by Bosch Rexroth Indramat for the VT-5000 IO Cards series. It follows Eurocard dimensions of 100 × 160 mm, occupies a 7 TE rack width, and has a 128.4 mm front plate, allowing direct insertion into DIN-standard subracks. A 32-pin DIN 41612 D connector routes supply lines, sensor signals, and solenoid drive outputs, while the module’s weight of 0.21 kg keeps cabinet loading low. Within an automation system, the card conditions feedback voltages and controls current to proportional solenoids, linking machine controllers with hydraulic actuators.

The card is powered by a nominal 24 V DC bus, and internal monitoring disables operation if the supply falls below 21 V or rises above 35 V. The logic electronics draw only 0.6 A, but transient peaks of up to 1.25 A are tolerated during switching events. A minimum enable level of 12 V allows the host PLC to apply a clean hardware release signal before pulse generation begins. The onboard oscillator runs at 5.4 kHz, producing a symmetrical waveform that the analog stage demodulates into the 3.6 V Dm2 reference used for valve position feedback. The monitored supply range helps prevent unstable operation when the available bus voltage is outside the card’s operating limits.

The output driver stage can deliver up to 2.5 A into a coil impedance of 2 Ω, providing the force required for medium-sized proportional solenoids. The secondary feedback loop references an Iw9 signal of 1 V, permitting rapid null adjustment without recalibrating the analog chain. The standardized Eurocard format supports installation in compatible control racks without requiring a separate mounting enclosure. Its low mass and narrow rack width help preserve space in densely populated control cabinets while the front plate provides accessible module handling.
