Product Description:
The VT 5041-21/1-0V is an I/O card produced by Bosch Rexroth Indramat for the VT-5000 IO Cards series. Installed in 19-inch system racks, the board conditions analog signals and drives solenoids so that proportional valves respond predictably to PLC commands. By translating sensor feedback into standardized levels and delivering controlled current to hydraulic coils, the module forms a bridge between electronic control units and hydraulic actuators in industrial automation.
The board is supplied from a nominal 24 V DC rail and draws a rated 0.6 A, leaving headroom for the maximum solenoid demand of 2.5 A that the onboard power stage can deliver. A crystal-controlled oscillator runs at 5.4 kHz, setting the carrier for pulse-width modulation of the output current. Incoming process variables pass through an analog input path with at least 50 kΩ of resistance, while a separate measuring socket presents 2 kΩ to portable meters for nonintrusive diagnostics. The enable circuit latches at a minimum of 12 V, and an internal comparator trips a pressure-fault channel at 11.5 V to protect machinery. When an alarm is generated, the message output can source 20 mA to drive an external indicator.
The PCB measures 100 × 160 mm and occupies a width of 5 TE behind a 128.4 mm front plate, aligning its physical format with Eurocard conventions. Signals and power are routed through a 32-pin male multipoint connector built to the DIN 41612 design D pattern, allowing straightforward backplane stacking. The current input burden on that connector is limited to 100 Ω, minimizing voltage drop from remote transmitters. The component has a mass of only 0.19 kg, which reduces the load placed on the card guides. The fixed board dimensions and connector arrangement support orderly installation within densely populated control cabinets.
