ROVER R-90Ex ATEX Explosion-Proof Digital Two-Way Radio Industrial Safety Communication Device

Advanced Technology

The R-90Ex operates on a UHF frequency range of 400–480 MHz, offering strong signal penetration in industrial facilities with dense infrastructure.

It supports ETSI TS 102 361 digital protocol, enabling:

• Clear digital voice communication
• Reduced interference
• Efficient spectrum utilization

With digital modulation (4FSK) and frequency stability of ±2.5 ppm, the device ensures consistent and accurate communication, even in mission-critical operations.

Security and Access Control Features

Security and control are central to the R-90Ex design. The device includes advanced features such as:

• Remote Disable/Enable – Prevent unauthorized use or lost device misuse
• Remote Monitoring – Supervisors can monitor field communication when required
• Emergency Alert System – Immediate distress signaling during critical incidents
• Busy Channel Lock (BCL) – Prevents interference and ensures communication clarity
• Private, Group, and All Call Modes – Flexible communication hierarchy

Additionally, man-down detection and lone worker functionality provide automated alerts in case of inactivity or emergencies, significantly improving workforce safety in isolated or dangerous environments.

High-Performance Design

The R-90Ex is engineered for high-performance operation under extreme conditions:

• Output Power: Up to 3.5W for extended coverage
• Battery Capacity: 2800 mAh for long operational shifts
• Low Power Mode: Extends battery life during standby
• Operating Current: <1300 mA for efficient energy usage

Its VOX (Voice Operated Transmission) capability allows hands-free communication, improving productivity in environments where manual operation is impractical.

Integration and Compatibility

Designed for seamless integration into modern communication infrastructures, the R-90Ex supports:

• Digital and Analog modes for backward compatibility
• Wide/Narrow Bandwidth Selection for flexible deployment
• Firmware Upgrade Capability for future scalability
• Talk Around Function for direct device-to-device communication without repeaters

This makes it suitable for organizations transitioning from legacy systems to advanced digital communication platforms.
