1 channel DI + 1 channel DO (supports AC250V 10A) LoRa Remote Transmission Terminal

● This terminal utilizes LoRa spread spectrum technology for wireless data transmission, offering users a fully transparent data transmission mode, high reception sensitivity of -139 dBm, superior anti-interference capabilities, and adjustable transmission power.

● It operates within the license-free ISM 430–490 MHz band—requiring no frequency usage fees—and defaults to 490 MHz to avoid the congested 433 MHz band.

● It offers a versatile configuration featuring one Digital Input (DI) and one Digital Output (DO), with status indicator LEDs provided for each channel.
Units can be deployed in pairs: when a DI input is triggered on one unit, the corresponding DO output is activated on the other.
Alternatively, a single LoRa gateway (or LoRa-to-RS485 converter) can connect to multiple LoRa wireless terminals to establish a one-to-many network topology.

● The device features automatic detection of the open/closed status for digital inputs; the digital output mirrors the exact state of the input, facilitating easy system commissioning.

● The digital output supports contact switching capabilities of 250 VAC/10 A, 125 VAC/15 A, and 28 VDC/10 A, and offers both Normally Open (NO) and Normally Closed (NC) output options.

● The DI/DOmaintains a stable state during power-up or when the fiber-optic link is disconnected, preventing any spurious or erratic switching behavior.

● It includes a dedicated USB (Type-C) configuration port, accompanied by configuration software that allows users to set LoRa parameters and monitor system status.

● It boasts robust lightning protection features, including resistance against direct strikes, induced high voltages, and power surges; the fanless design ensures efficient heat dissipation and minimizes downtime for repairs.

● It supports flexible installation options, including standard 35 mm DIN rail mounting or wall mounting; designed for wide-temperature operation, it functions reliably within a range of -40°C to +85°C.

● It supports a wide-range power input of 9–50 VDC (compatible with both AC and DC sources), and both the power interface and the DI/DO ports feature 6 kV lightning surge protection.

● The power supply circuit incorporates overload protection and reverse-polarity protection, and the device fully complies with Level 4 industrial electromagnetic compatibility (EMC) requirements.

● It features superior lightning protection capabilities, offering defense against direct strikes, induced high voltages, power surges, and similar electrical transients.
