1 Introduction

1. This product is a pair transmission function product. Function: The transmitter collects 4 channels of analog
signals (0/4 to 20mA) and transmits the data to the receiver via wireless (LoRa spread spectrum), and the receiver
restores 4 channels of analog signals (0/4 to 20mA).
2. Model No. K62-DL20, including transmitting (collecting) end: K62D-40RL20; receiving (reducing) end:
K62D-04RL20.
3. The module also has a 485 data pass-through function. The 485 data from the transmitter and receiver can be
transmitted through LoRa wireless communication.
4. The product is highly easy to use, avoiding long-distance cable distribution, greatly reducing enterprise
labor/material costs, and reducing construction and maintenance difficulties.
5. For industrial users, all industrial grade design, after extensive testing, stable and reliable quality.
6. Construction-free installation: It can replace the link cable and transmit far away, eliminating the trouble of cable
construction.
7. Programming-free design: no programming required, all parameters can be configured through the upper
computer software, easy to use and reliable operation.
8. Automatic error correction: The terminal has strong error correction capability and can actively correct the
interfered packets, greatly improving transmission reliability.
