Product Overview
MODBUS 8-channel NTC temperature acquisition moduleIt is a temperature data collector that can simultaneously connect 8 NTC10K thermistor probes. Each channel independently collects data and reads all 8 temperature values at once through RS485 Modbus RTU, greatly simplifying the wiring and data acquisition of multi-point temperature monitoring systems. Widely used in data center cabinet temperature control, cold chain logistics, industrial drying, grain warehouse temperature measurement and other scenarios that require multi-point synchronous temperature measurement.
Why choose route 8?
Traditional solution: Each temperature measurement point is equipped with a sensor, a transmitter, and an ADC channel → 8 points require 8 analog inputs. MODBUS scheme: 8 NTC probes → 1 module → 1 RS485 channel → all 8 temperature data channels. The wiring has been reduced from 16 to 4 (DC+-, A, B).

HA Integration
Directly maps 8 temperature channels into 8 sensor entities through Modbus integration, and displays 8 temperature curves on the HA dashboard. Typical application: Monitoring the inlet/outlet air temperature of 8 cabinets in a data center simultaneously; The temperature of 8 storage locations in the cold storage is independently monitored and recorded.
