EElink - TK121‑S

TK121‑S GPS Tracker

The TK121‑S is a compact, value‑focused GPS tracker designed for vehicle fleets that need reliable, Plaspy compatible real‑time tracking without unnecessary complexity. Built as an enhanced version of the TK121, it delivers GPS/LBS dual‑mode positioning with AGPS assistance, ACC (ignition) detection, configurable geofencing, and movement/speed alarms — all tailored for quick integration into Plaspy's fleet management workflows.

Weighing just 31 g and measuring 85.8 × 30.6 × 10.8 mm, the TK121‑S provides fleet managers with consistent telemetry and low power consumption across a wide input range (9–72 V). The tracker supports MoveLink protocol 1.9/2.0 for seamless data exchange and remote configuration via platform, app, or SMS, making it an efficient choice for anti‑theft, immobilizer workflows, and basic fleet telemetry on Plaspy.

Key Highlights

• Plaspy compatible: native support for MoveLink protocol 1.9/2.0 simplifies integration into Plaspy for real‑time tracking and reporting.
• Dual‑mode positioning (GPS + LBS) with AGPS for faster fixes and improved coverage in urban or marginal signal areas.
• Ignition (ACC) detection and optional relay to enable remote cut‑off/immobilizer features for anti‑theft protection.
• Built‑in displacement and speed alarms plus geofencing for automated fleet alerts and incident detection.
• Ultra‑compact, lightweight form factor ideal for discreet vehicle installation and asset tracking.
• Low current draw (25 mA active, 5 mA standby) and a 70 mAh backup battery for power‑loss alerts and reliable telemetry.
• Remote configuration via platform/app/SMS reduces onsite maintenance and accelerates deployment at scale.

How It Works with Plaspy

When integrated with Plaspy, the TK121‑S streams location and event data using MoveLink protocol 1.9/2.0 so you get continuous real‑time tracking, configurable alerts and historical reports. Plaspy ingests the tracker’s GPS/LBS positions, ACC status, and alarm events, presenting them in dashboards, route playback, and automated notifications.

• Real‑time location and telemetry updates delivered to Plaspy for live map views and reporting.
• ACC/ignition status reporting to track engine on/off cycles and support ignition‑based rules.
• Displacement, speed and geofence alarms to trigger immediate alerts and event logs in Plaspy.
• Optional relay support for remote cut‑off (immobilizer) workflows controlled from Plaspy or via SMS.
• Works with Plaspy platforms that orchestrate Bluetooth sensors and beacons — the tracker feeds core telemetry while the platform associates external sensor data for fuel monitoring and temperature tracking workflows.

Technical Overview

Use Cases

• Fleet management for light commercial vehicles — monitor routes, speeds, and ignition events to improve utilization and driver accountability.
• Anti‑theft and immobilizer workflows — use ACC detection plus the optional relay to remotely cut off vehicle power when unauthorized movement is detected.
• Geofence and movement alerts — automate notifications for unauthorized exits/entries or unexpected displacement of assets.
• Telemetry enrichment and fuel monitoring workflows — pair TK121‑S telemetry with external fuel sensors and Plaspy dashboards to support fuel control programs.
• Discrete asset tracking — the small size and low weight make it suitable for tracking trailers, equipment and other mobile assets that benefit from real‑time location data.
