Bosch Rexroth VEP40.3CEN-256NN-MAD-128-NN-FW – Compact Industrial HMI for Reliable Machine Visualization

• Warranty: 365 days from delivery

• Lead time: 1 week if in stock; no more than one month at the latest

• Payment: 50% advance payment; full payment before delivery

• Shipping: FedEx, UPS, DHL express options

• Windows CE runtime (CEN) – Boots quickly and runs stable HMI applications with low overhead.

• 128 MB RAM (MAD-128) – Sufficient for typical HMI projects, alarm lists, and trend pages.

• 256 MB Flash (256NN) – Non-volatile storage for runtime, recipes, and application files.

• 24 VDC industrial power – Fits standard machine panels and cabinet power rails.

• Panel-mounted design – Sealed front for dusty shop floors; easy to service from the front.

• Ethernet and serial connectivity – Commonly used to link with PLCs and drives for data exchange.

• Resistive touchscreen – Works well with gloved hands and is easy to calibrate.

• Rexroth ecosystem compatibility – Plays nicely with IndraControl and third-party PLCs in many cases.

I typically see the VEP40.3CEN in small to mid-size machines where operators need clear screens, quick alarm handling, and recipe management without a full-blown IPC. Common scenarios include packaging lines, parts assembly cells, metalworking and CNC auxiliaries, conveyors, and plastics equipment. One customer in food packaging told us the resistive touchscreen “just keeps working with gloves and sanitizer,” which seems to be a frequent theme on busy lines.

• Reliability first – Windows CE runtime and solid-state storage reduce unplanned stops.

• Easy PLC connectivity – Ethernet and serial options cover most brownfield integrations.

• Lower total cost – No rotating media; minimal OS maintenance; simple spare strategy.

• Lifecycle fit – Rexroth platform support and long-term availability in many regions.

• Straightforward commissioning – Quick boot, simple backups, and predictable behavior.

• Cabinet standards – Mount on a flat, rigid panel; maintain IP65 seal with the provided gasket.

• Ventilation – Allow rear clearance for heat dissipation; avoid direct exposure to oil mist or steam.

• Wiring – Use a stabilized 24 VDC supply with proper grounding; segregate network/serial lines from power cabling.

• Safety – De-energize before servicing; observe ESD precautions when handling connectors and storage media.

• Routine care – Clean the front with non-abrasive wipes; periodically recalibrate the touch if drift appears.

• Software upkeep – Keep backups of the runtime and project; apply vetted firmware updates during scheduled downtime.

• Certifications: CE and RoHS compliant; UL recognition is common for this class of HMI in many markets.

• Manufacturing quality: Produced under ISO 9001 quality systems.

• Warranty: 12 months (365 days) standard coverage.

• 24 VDC DIN-rail power supply (industrial grade, low ripple)

• Ethernet patch leads and shielded serial cables (RS‑232 / RS‑485 as required)

• Rexroth-compatible memory card for backups and firmware images

• Panel mounting kit and replacement front gasket for maintaining IP rating

If you’re replacing an existing VEP40.3 unit, a quick check of the nameplate helps confirm interface options. In most cases, projects migrate over smoothly, and commissioning time stays predictable.
