End of life
Teltonika stopped taking orders for the Teltonika RUT955 on 31 July 2023 and supports it until 31 July 2028. The official replacement is the Teltonika RUT906. These use the same 4-pin socket, so our cables fit them too.
About the Teltonika RUT955
The RUT955 was the RUT9 model with everything: GNSS, RS232, RS485, USB and an extra I/O block on top of four Ethernet ports and dual SIM. It has reached end of life, but it was a favourite in transport and utilities, so a lot of them are still bolted in place.
Many sit in buses, trams and pumping stations where the router is hard to reach, so a reliable power lead matters.

|---|---|---|
| 1 | Power (+) | Red |
| 2 | Ground (-) | Black |

How much power the RUT955 draws
With everything busy, Teltonika's figure for the Teltonika RUT955 is 9.2 W at 12 V, and about 2 W at rest. Even that peak leaves 8.8 W spare on the 18 W supply. At 24 V Teltonika lists a peak of 9.3 W.
Which cable should I pick?
- Wall socket. For a desk, a shop or any spot with a wall socket. Uses about 51% of the supply at peak.
- Vehicle. For 12 V cars and 24 V trucks, passing 9 to 30 V straight through.
- Cabinet, battery or solar. For DC rails, batteries and solar. Green and white bring out the I/O. Add a 2 A slow-blow fuse near the source.
Install tips
- On vehicles, the RUT955 was often wired straight to the 24 V supply. When you replace the cable, add surge protection if there was none before, because 24 V systems can spike above 30 V at engine start.
- On 24 V vehicles, add surge protection. Truck and bus systems can spike well above 30 V at engine start, and the Teltonika RUT955 is only rated to 30 V.
- Do not let the cable hang from the plug. A cable tie a few centimetres from the socket stops vibration from working it loose.
Teltonika RUT955 power FAQ
?What voltage does the Teltonika RUT955 need?
The Teltonika RUT955 accepts 9 to 30 V DC on its 4-pin socket. That covers 12 V and 24 V systems, but not 48 V.
?Does the Teltonika RUT955 come with a power supply?
New units usually ship with a 9 V wall adapter. A second cable makes sense for spares, a second site, or an install where a wall plug is not practical, such as a vehicle or a DIN rail cabinet.
?What replaces the Teltonika RUT955, and does my cable still fit?
Teltonika's official replacement is the RUT906. It keeps the 4-pin socket and the 9 to 30 V range, so the cable stays the same.
?Can I use the input and output on the Teltonika RUT955 with your cable?
Yes. Teltonika labels pins 3 and 4 on the Teltonika RUT955 as I/O, and our screw terminal cable brings them out on the green and white wires.
?Is the 18 W supply strong enough for the Teltonika RUT955?
Yes. The Teltonika RUT955 peaks at 9.2 W on 12 V, about 51% of the supply's rating.
?Do you sell the Teltonika RUT955 itself?
No. We only make the power cables and the supply. The Teltonika RUT955 is sold by Teltonika's distributors.
