Bosch Rexroth VT‑MVTW‑1‑16D – 16‑channel monitoring/test card for VT rack-based hydraulic control
The Bosch Rexroth VT‑MVTW‑1‑16D is a plug‑in monitoring and test module designed for Rexroth VT series rack systems used around proportional and servo‑hydraulic controls. From my experience, it’s typically applied as a multi‑channel status and alarm supervisor: you wire in valve solenoid signals, limit switches, or other 24 V logic points, and the card gives you clear, front‑panel indication and consolidated warning outputs for the machine control. You might notice that commissioning gets faster—technicians can see signal states immediately and trace faults without digging into the PLC first.
In many cases, maintenance teams keep one of these as a spare to minimize downtime on older VT 19″ rack installations. It seems to be a straightforward fit when you need reliable 16‑point monitoring with simple wiring and robust industrial behavior.

Key Features
- 16 digital monitoring channels – Typically used for 24 VDC logic from valve coils, pressure/limit switches, and interlocks.
- Front‑panel status indication – LEDs for quick signal checks; technicians can pinpoint wiring or device issues faster.
- Alarm/test functionality – Consolidated warning output(s) and simple test access for commissioning and periodic checks.
- Rexroth VT rack compatibility – Eurocard format for 19″ subrack systems (DIN 41612 connector, typical for VT cards).
- 24 VDC control power – Stable low‑voltage operation suited to industrial cabinets.
- Industrial build – Designed for hydraulic environments where noise immunity and clear diagnostics matter.

| Operating Temperature | 0…50 °C typical for control electronics (non‑condensing environment) |
| Signal I/O Types | 16 × digital inputs (24 V logic); status LEDs; alarm/test output(s) for supervisory signaling |
| Communication Interfaces | Not applicable (rack card with local indication; no fieldbus in most cases) |
| Installation Method | Plug‑in Eurocard for Rexroth VT 19″ subrack; DIN 41612 backplane connector |
Where it fits nicely
- Hydraulic power units that need simple, reliable interlock and valve‑coil monitoring.
- Proportional valve systems where operators want front‑panel feedback during setup.
- Retrofits on Rexroth VT racks to standardize diagnostics and reduce nuisance trips.
One thing I appreciate is how maintenance techs typically use the LEDs to isolate if the fault is wiring, sensor, or PLC logic. A customer recently mentioned that swapping in a spare VT‑MVTW card cut their troubleshooting time in half during a line restart after a shutdown.
Related / Supporting Products
- Rexroth VT 19″ Subrack (VT series) – Required chassis for Eurocard installation; provides the DIN 41612 backplane.
- Rexroth VT power supply card (24 VDC rack supply) – Stable feed for control cards; ensures proper backplane distribution.
- Rexroth VT proportional valve amplifiers (e.g., VT‑VSPA series) – Often used alongside VT‑MVTW for complete valve control plus monitoring.
- Wiring harness/backplane connectors (DIN 41612) – For clean, serviceable connections to the I/O points.
If you’re consolidating channels, a lower‑count variant (8 channels) is sometimes used in smaller panels, while the 16D keeps things compact when you’ve got more interlocks on a single rack. Selection usually comes down to cabinet space and the number of valve/switch signals you really need to see on the front panel.
Installation & Maintenance
- Cabinet & rack – Mount in a 19″ VT subrack with proper grounding. Keep 50 mm clearance for airflow; avoid heat sources.
- Power & wiring – Use a regulated 24 VDC supply. For inputs, standard 24 V control wiring with ferrules helps. Separate I/O from motor cables to reduce noise.
- Safety – Isolate power before inserting/removing the Eurocard. Verify correct slot/backplane orientation to prevent pin damage.
- Commissioning – Check each input LED and the alarm/test outputs. From my experience, labeling the front panel positions saves a lot of time later.
- Routine care – Quarterly visual checks for loose connectors; clean dust with dry air; reseat the card annually if cabinets are subject to vibration. If the version provides trim pots or test points, note settings in maintenance logs.
