USR-DR154 RS485 to 4G LTE CAT-1 Din Rail 4G LTE modem

Key Features of USR-DR15X/DR154 Modem

1. Network Compatibility & Performance
Supported Networks:
LTE CAT 1: Optimized for IoT with 10 Mbps downlink / 5 Mbps uplink, ideal for applications requiring moderate data rates.
Bands: Supports 1/3/5/8/34/38/39/40/41 (covers global LTE-FDD and LTE-TDD bands), ensuring compatibility across regions.
Fallback to 2G/3G: Maintains connectivity during LTE network transitions (where legacy networks are still active).

2. Hardware Design
Ultra-Compact Form Factor: Small footprint for easy integration into space-constrained IoT devices (e.g., sensors, trackers).
External SIM Slot: Enables easy SIM card replacement without disassembling the device.
Wide Voltage Input: Supports industrial-grade power supply (e.g., 5–36V DC), suitable for harsh environments.
RS485 Interface: Facilitates communication with industrial equipment (PLCs, sensors, meters) for data collection/control.

3. Power Efficiency
Optimized for low power consumption, making it ideal for battery-operated IoT devices (e.g., remote sensors, wearables).

4. Software & Upgradability
FOTA (Firmware Over-The-Air): Enables remote firmware updates to enhance security, add features, or fix bugs.
FTP Support: Allows bulk data transfers or configuration updates via standard FTP protocols.

5. Industrial Reliability
Robust Construction: Built for industrial environments with extended temperature ranges, EMI shielding, and vibration resistance.
Low Latency: Critical for real-time applications like remote control or emergency alerts.
