Product Details
Military-Grade LoRa Modulation — 30dBm / 10km Range
The EWD95M employs LoRa spread spectrum technology with up to 30dBm output power, achieving reliable communication over 10km in open environments. Its strong anti-interference capability makes it ideal for electrically noisy industrial sites such as factory floors, substations, and outdoor utility installations.
Transparent RS485/RS232 Interface — Plug-and-Play Integration
Supports transparent serial data transmission over RS485 and RS232, enabling seamless integration with PLCs, sensors, meters, and SCADA systems without protocol conversion. Multiple transmission modes and AT command configuration via USB tool simplify deployment.
Triple-Proof Industrial Design — DIN-Rail Mounting, 8–28V Wide Voltage
The plastic enclosure is sprayed with triple-proof coating (anti-mold, anti-humidity, anti-salt spray), rated for -40℃ to +85℃ continuous operation. Standard DIN-rail mounting fits directly into industrial control cabinets. The 8–28V DC wide-voltage input accommodates diverse power sources including 12V and 24V industrial supplies.

FAQ
Q: Is the EWD95M compatible with Ebyte E22 series LoRa modules?
A: Yes. The EWD95M is designed to intercommunicate directly with Ebyte E22 series modules operating in the same frequency band, enabling mixed deployments of DTUs and bare modules within the same network.
Q: What is the maximum communication range of the EWD95M?
A: Up to 10km in open line-of-sight conditions at 30dBm output power using LoRa modulation. Actual range depends on environment, antenna gain, and obstacles.
Q: How do I configure the EWD95M for my application?
A: Configuration is done via AT commands through the RS485/RS232 interface using Ebyte's USB configuration tool (PC software provided). Parameters include frequency channel, air data rate, transmit power, and transmission mode.
Q: Can the EWD95M operate on 12V or 24V industrial power supplies?
A: Yes. The 8–28V DC wide-voltage input supports both 12V and 24V industrial power rails without any additional voltage regulation, simplifying cabinet wiring.
Q: What does the triple-proof coating protect against?
A: The three-proof (三防) coating protects the internal PCB against mold growth, high humidity/condensation, and salt spray corrosion — critical for outdoor enclosures, coastal environments, and high-humidity industrial sites.
Q: Does the EWD95M carry CE and RoHS certifications?
A: Yes. The EWD95M series holds CE (RED), RoHS, and SRRC certifications, enabling direct deployment in EU markets and compliant use in Chinese regulated frequency bands.
