LM200 - LoRa Master /Modbus RTU Client Agent, Group IO Mapping, Logic Rule
LC144 - LoRa End-Node, 8CH AIO, 1 Modbus RTU 485 Host
LoRa Modbus Controller - Analog Input Output Logic Controller for Pair and Group Analog I/O Mapping
Transparent LoRa Modbus Extension (Two-way Communication)
LM200 acts as a LoRa master to communicate with up to 250 LC144 nodes via Modbus/RTU over LoRa, enabling remote analog I/O mirroring and control.
Versatile Analog Inputs & Outputs
LC144 supports 2 × 0–10 V inputs, 2 × 4–20 mA inputs, 1 × 0–10 V open-collector voltage output, 1 × 4–20 mA current output, and 2 × PWM outputs (0–5 V or 0–10 V) with high precision.
Smart I/O Mapping & Logic Control
Configure analog tracking rules (V/V, V/A, A/A, A/V) via user utility to map input channels to outputs across devices; supports up to 20 rule entries.
Long LoRa Communication Range (Up to 6 km)
Operates reliably over distances of 3–6 km (depending on terrain) with configurable spreading factors (SF6–SF12).
Secure Radio Link with AES-128 Encryption
Protected data transmission using 128-bit AES encryption with configurable encryption keys and echo/re-send mechanisms for reliability.
Reliable Industrial Operation
LM200 and LC144 support wide power input (10–30 VDC), consume low power (~1 W LM200; ~3 W LC144), and operate in –40 °C to +75 °C environments.
Event Logging & Monitoring (LM200)
LM200 logs up to 1,000 events (e.g. polling failures), and supports online monitoring, rule editing, and diagnostics via Windows LoRa utility.
User-Friendly Configuration via Micro-USB Utility
Simple PC-based setup with model auto-detection, analog I/O parameter configuration, firmware updates, and rule chain editing.
PWM Output with High Accuracy
PWM channel supports 5 V (200 mA) or 10 V open-drain outputs at 100 Hz–1 kHz with 0.2% duty-cycle accuracy for dimming or control applications.
Compact DIN-Rail or Wall Mount Enclosure (IP40)
Lightweight plastic housing (~115 g, ~26 × 102.5 × 72 mm) with industrial-grade EMC compliance and secure mounting options.
