SLET1000-S is a remote digital temperature acquisition system that can simultaneously connect 120-240 digital temperature sensors. It has a secondary development communication protocol, sensor bus wiring, convenient networking, and supports 120-240 DS18B20 measurement points.
The SLET1000‑S is a remote digital temperature‑data acquisition system that can connect up to 120‑240 DS18B20 sensors via a bus‑type wiring scheme. It communicates with a host PC through RS232 and optionally CAN, RS485 or Ethernet, providing real‑time temperature readings.
The manual covers the device’s features, technical parameters, wiring instructions, command set for reading and configuring sensors, and a bill of materials. It also describes how to expand the sensor bus, power requirements, and troubleshooting of communication errors. This manual is written in Chinese.

It can connect 120‑240 DS18B20 sensors, distributed over 10 channels with up to 12‑24 sensors per channel.
The standard interface is RS232, and optional CAN, RS485 or Ethernet modules can be added for longer distances.
It uses a DC 5 V supply rated at 1 A; for many sensors or long cables a 2 A‑3 A supply is recommended.
