About the Teltonika RUT241
The RUT241 is the closest like-for-like follow-up to the RUT240. It shares the 83 x 25 x 74 mm housing, the two Ethernet ports and the 2.4 GHz Wi-Fi, and Teltonika's wiki says RUT240 documentation also applies to it. Teltonika also offers it in a version with eSIM.
Installers like it because it drops into the same DIN rail clip and cut-out as the RUT240 it replaces.

How much power the RUT241 draws
Teltonika's power table puts the Teltonika RUT241 at 1.1 W idle and 3.3 W flat out at 12 V. In current that is about 273 mA, against the 1500 mA our supply can give. On a 24 V supply the peak is about 3.2 W.
Which cable should I pick?
- Wall socket. A replacement for the original adapter, with 14.7 W of spare capacity.
- 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
- Upgrading from a RUT240? Keep the same cable. The pin layout is identical, so even an input or output you wired on the old router works the same way.
- On 24 V vehicles, add surge protection. Truck and bus systems can spike well above 30 V at engine start, and the Teltonika RUT241 is only rated to 30 V.
- Insulate any wire you do not use. A loose green or white wire touching the cabinet can trigger an input or short an output.
Teltonika RUT241 power FAQ
?Can I run the Teltonika RUT241 on 12 V or 24 V?
Yes, both. The input range is 9 to 30 V DC, fed through the 4-pin power socket.
?Does the Teltonika RUT241 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.
?My Teltonika RUT241 came with a 9 V adapter. Is a 12 V, 18 W supply too strong?
No. The RUT241 accepts anything from 9 to 30 V, and a supply only delivers the current the router asks for. At its busiest the RUT241 takes about 3.3 W, so our supply runs well within its rating.
?Can I use the input and output on the Teltonika RUT241 with your cable?
Yes. The screw terminal cable brings pin 3 (digital input) out on the green wire and pin 4 (digital output) on the white wire. Configure them in RutOS under Services, Input/Output.
?Does Smart Power Cable sell Teltonika routers?
Not the router, no. We are an independent maker of power cables. The Teltonika RUT241 is a Teltonika product sold through their own channels.
