Neousys MezIO-V20/V21 Ignition Power Control MezIO Modules for 12 V and 24 V Vehicles

A computer in a vehicle has to follow the ignition. It should start when the engine starts, ride out a short stop or a stall, shut down cleanly when the vehicle is parked and draw almost nothing from the battery overnight. Getting that wrong means corrupted files, flat batteries or a system that is not ready when the shift starts. The Neousys MezIO-V20/V21 series handles ignition power control from a module inside the computer, so there is no separate ignition controller or timer relay to wire and mount behind the dashboard. Because the delay modes are predefined, setting up a fleet of vehicles to behave the same way is a matter of choosing the same mode on each system.

All three modules mount inside the host on a high-speed board-to-board connector with three-point mezzanine mounting, using the one MezIO interface each Neousys system provides. Each provides ignition power control with predefined power-on and power-off delay modes, so the start-up and shut-down delays can be set to suit the vehicle without custom software. Ignition-off standby draw is an ultra-low 12 mA. Advanced features cover low-battery protection, guarded power-on and power-off delay durations, system hard-off and a BIOS POST check. The modules support 12 V DC small vehicles and 24 V DC buses and trucks. On the MezIO-V20 and MezIO-V21, the mode is chosen on a rotary switch on the rear panel, and low-battery protection shuts the system down if the input stays below 11 V on a 12 V supply or 18 V on a 24 V supply for 60 seconds.

The series has three modules, matched to different host computers. The MezIO-V20-EP provides the ignition control on its own for the Nuvo-9000E/P/DE, Nuvo-11000E and Nuvo GC computers. The MezIO-V20 adds one full-size mini PCIe socket wired for USB 2.0, with a SIM socket, for USB-based cellular or GPS cards. The MezIO-V21 adds a full-size mini PCIe socket wired for both PCIe and USB 2.0, also with a SIM socket, so it takes cards that need either interface.

We fit the MezIO-V20/V21 module that suits your host inside the Neousys computer, set the ignition delay mode and test the build before it ships. The MezIO-V20-EP fits the Nuvo-9000E/P/DE, Nuvo-11000E, Nuvo-11160GC, Nuvo-9160GC and Nuvo-9166GC, and on the Nuvo-11531/11588 it is fitted as the optional ignition power control, which we confirm with the quote. The MezIO-V20 fits the POC-900, POC-700 and POC-700-FT plus the Nuvo-9000LP and Nuvo-11000LP, and the MezIO-V21 fits the same computers plus the POC-600. Typical uses include buses, trucks, fleet and service vehicles.
