Choose your RTCU hardware

Start with the interfaces.
Find the right fit.

Narrow the range by the connections, enclosure and application your installation needs. Compare the practical differences, then open the model’s technical information.

Compare the models.

USB service is the programming connection; USB host connects peripherals. Features marked “option” require equipped hardware. LX5 DIN-rail mounting is a separately ordered version.

Filters work together: each result must include every required interface and match the other selected options. Clear filters to see all models.

One platform, different hardware

Families are a starting point.

Choose by the exact interfaces, I/O and installation. A shared family or execution architecture does not make two models electrically interchangeable.

LX: choose the interfaces and installation

NX32L models cover vehicle gateways, compact installations and industrial I/O. LX4 pro V2 serves wired M-Bus installations; LX9 models provide relay I/O. Related eco and pro/ultra models have different connectivity and I/O.

NX: vehicle, DIN-rail or industrial I/O

NX32L models use distinct enclosures and interfaces: NX-200 for vehicle connections, NX-400 evo for DIN-rail I/O with a touchscreen, and NX-900 for relay and analog I/O.

MX: the NX32 development path

MX2 turbo LTE combines regional LTE Cat. 1, GNSS and CAN on the NX32 architecture. Its classic Emulator workflow differs from the NX32L models; choose the development path for the exact device.
