Teltonika PR5MEC21 4-Pin Power Adapter – I/O Control at

The Teltonika PR5MEC21 is a 4-pin power adapter that unlocks input/output control on your Teltonika router. Instead of just powering your device, this adapter lets you connect sensors, switches, and external equipment directly—turning your router into a mini-controller for industrial and professional setups.

Connect sensors and control equipment through your router

• Screw-terminal block design works without soldering or crimping—ideal for field installations and cabinet wiring.
• Configurable I/O pins let you monitor door sensors, liquid alarms, or trigger gate and lock controls via SMS or the RMS app.
• Compatible with all major Teltonika device ranges: RUT and RUTX router series, plus TRB gateways.
• Vehicle ignition detection ready—connect to your fleet router so it powers on or alerts only when the engine starts.

Perfect for installers, fleet managers, and industrial automation projects where you need clean, reliable I/O integration without custom wiring.
