DIN Rail-Mount 4G DTU for RS485 to LTE CAT1, Industrial Wireless DTU

Optimized Control Panel Footprint

✓ Ultra-Compact DIN-Rail Profile: Only 37.6mm width, saving approximately 75% of horizontal panel space compared to traditional wall-mounted cellular modems.

✓ 256KB Non-Volatile Historical Cache: Integrated offline memory buffers serial telemetry autonomously during base station dropouts, uploading timestamped historical frames sequentially upon restoration of cellular linkage.

Core Edge Computing Logic

✓ Native Modbus-to-JSON Parsing: Actively queries attached RS485 slaves and encapsulates hex register data into structured HTTP/MQTT JSON payloads directly at the OT edge.

✓ Bandwidth Reduction Algorithms: Integrates threshold limit alarms, register scaling, and “Data Change Uploads” to push telemetry strictly when operational anomalies occur.

✓ Hardware Watchdog Protection: An independent watchdog circuit continuously supervises system execution, triggering zero-touch automated resets if mobile network linkage stalls.

Mission-Critical SCADA Applications

✓ Unmanned Telemetry Substations: Provide continuous telemetry for distributed smart grids, solar tracking arrays and remote hydrological monitoring loops.

✓ Severe Outdoor Survival: Fully certified to operate stably under harsh ambient temperatures from -40°C to +85°C, housed in industrial flame-retardant alloy plastic chassis.
