Watts Otto?

Seven modules, on purpose

Most DIN rail meters squeeze into three modules. Otto takes seven, and uses the space for a display you can read, an optical port, and a bay for the communication module.

Direct or through transformers

Otto comes in two versions, for direct connection and through instrument transformers. Ten terminals along the bottom edge, each with two screws, take the three phases and neutral, with three inputs and three outputs on spring terminals beside them.

Pull a red cable end out of its terminal and watch the display: L1 to L3 follow the phases, R1 to R3 the outputs.

Probe on the front

Hold the optical probe to the port. It connects over Bluetooth, so there is no cable between you and the cabinet.

Everything behind the front

Otto is our own hardware, made in the EU. Five layers, from the cover you see to the base that holds the rail.

Built for the cabinet

It clips onto a standard 35 mm rail. The terminal cover and metrological seal protect the connections, and the communication module plugs in at the top right, above the optical port.

Firmware that speaks DLMS

Registers, profiles and events are available over DLMS, the same way as on any other meter in your system. Use the keys to page through the display.

Every setting in one place

The parametrisation software connects through the Bluetooth probe. Check the clock and identity, set tariffs, load profiles and display lists, manage security keys and update the firmware.

Ready for CMC and OuroPlatform

CMC, the Collector Mobile Client, reads Otto on site through the Bluetooth optical probe. OuroPlatform manages it remotely, alongside the rest of your meters.

Otto is a prototype

It exists, it measures, and it is still changing. The details on this page are a draft. If Otto could fit your meter fleet, write to us.
