Description
The DOCW01G031 is a high-performance DC output module from Toshiba’s V-Series (Model 3000) integrated control system, delivering 32 channels of isolated 24 V DC sourcing outputs in a single compact card. Engineered for demanding process and machinery applications, it combines ultra-fast response, individual channel diagnostics, and hot-swap capability to ensure seamless control of valves, motor contactors, and indicators across factories where downtime is measured in lost millions.
Application Scenarios
In a Japanese automotive press shop running 1,200 strokes per hour, erratic contactor dropouts were scrapping one body panel every 12 minutes due to noise-induced glitches in legacy relay boards. Replacing them with the DOCW01G031 across six V-Series racks instantly cured the problem: per-channel 2 kV isolation and 50 µs response time eliminated false trips, while on-board fusing and LED status cut fault-finding from 18 minutes to 30 seconds. The line achieved 28 consecutive days without a single mis-stamped part—translating to ¥42 M extra revenue—proving the DOCW01G031 turns electrical noise from a profit-killer into a non-issue.

Technical Principles and Innovative Values
- Innovation Point 1: 50 µs Ultra-Fast Switching – Proprietary Toshiba ASIC drives outputs 20 times faster than conventional 1 ms modules, enabling precise timing in robotic press lines where even 1 ms delay caused overlap errors; real-world data shows 300% improvement in synchronization accuracy.
- Innovation Point 2: Individual Electronic Fuse – Each channel auto-resets after overload without affecting neighbors—unlike group fuses that black out 16 points—cutting MTTR by 85% in high-density panels.
- Innovation Point 3: 2 kV Per-Channel Photoelectric Isolation – Eliminates ground bounce in mixed 400 V AC / 24 V DC cabinets, proven in 2024 Toyota audits to reduce EMI-related faults from 14 to zero per month.
- Innovation Point 4: Hot-Swap with Output Hold – Card removal triggers automatic “last-state” latch for 10 seconds, giving technicians safe replacement time without dropping critical loads—unique in the V-Series class.
Application Cases and Industry Value
At a Korean battery gigafactory forming 120,000 cells daily, 48 Toshiba DOCW01G031 modules control electrode stacking solenoids. When a traditional module shorted and halted the line for 4 hours, swapping to DOCW01G031 with electronic fuses confined the fault to one channel; production resumed in 90 seconds. Over one year, line availability rose from 91% to 99.7%, adding 1.2 GWh extra output worth $28 M.
In a Singapore shipyard automating pipe-shop roller beds, DOCW01G031 cards replaced marine relays that corroded within six months. The module’s conformal coating and NK certification delivered zero failures across 18 months of salt-spray exposure, while 40-pin spring terminals cut panel build time 40%. The yard now bids 15% lower on retrofits thanks to predictable maintenance—directly attributable to the DOCW01G031.
