Teltonika PR5MEC21 4-PIN Power Adapter With I/O Access

PR5MEC21

The Teltonika PR5MEC21 4-Pin Power Adapter with I/O Access is a compact, well-engineered cable adapter that converts a standard 4-pin power plug into a flexible 4-pin screw-terminal block. In doing so, it allows access to the built-in input/output (I/O) functionality on compatible Teltonika devices.

This adapter is ideal for installations where you need both a safe, reliable power feed and also want to use I/O ports for digital inputs or outputs — for example alarm signals, sensor triggers or remote restart controls. Installation is straightforward, with screw-terminal wiring and a 100 mm, 4-core 24 AWG cable. At just 15 g, the adapter is lightweight, compact and unobtrusive — perfect for DIN-rail cabinets, enclosures, or retrofit jobs where space is tight but functionality matters.

Using a genuine Teltonika adapter ensures reliability and correct pin-out, avoiding many of the common issues caused by generic connectors. This makes PR5MEC21 the go-to choice where stable power and I/O integration are needed in M2M, IoT, industrial, CCTV or remote gateway deployments.

Key Features

• 4-pin to 4-pin power adapter with screw-terminal block input
• Enables configurable digital I/O access on supported devices
• Cable: 4 × 0.20 mm² (24 AWG), length ~100 mm
• Accepts conductor cross-section: 0.14–0.50 mm² (solid or flexible), or 0.25–0.30 mm² (ferrule with sleeve)
• Compact, lightweight (approx. 15 g) and easy to install
• Durable black casing — unobtrusive and blend-in design
• Suitable for industrial, M2M and IoT installations

Typical Applications

• Feeding power to routers, gateways and switches while preserving I/O functionality
• Industrial control panels and automation enclosures
• Remote telemetry, SCADA, sensor networks, metering, EV-charge stations
• CCTV and security systems requiring remote alarm / trigger connections
• Retrofit of existing Teltonika installations where custom wiring or I/O use is needed

Compatibility

PR5MEC21 is compatible with a broad range of Teltonika devices using a 4-pin power connector with I/O support, including (but not limited to):

• RUT series routers (e.g. RUT200, RUT241, RUTx series)
• TRB series gateways
• TSW series switches with 4-pin power socket

Check the device’s power-connector type and I/O availability before use — but in most standard industrial Teltonika installs, this adapter provides the easiest way to unlock I/O while maintaining a proper power feed.
