32-Channel Digital Temperature Acquisition Module – RS485 Modbus RTU
Monitor up to 32 temperature points simultaneously with this high-density RS485 temperature acquisition module. Using digital temperature sensors and Modbus RTU communication, it is ideal for PLC, SCADA, BMS, and industrial monitoring applications requiring multi-point temperature measurement.
This 32-Channel Temperature Acquisition Module is designed for applications requiring large-scale, multi-point temperature monitoring from a single device.
The module supports up to 32 digital temperature sensors, providing stable and accurate temperature readings without the signal drift commonly associated with analogue inputs. Temperature data is transmitted via RS485 using the Modbus RTU protocol, allowing seamless integration with PLCs, RTUs, HMIs, SCADA systems, and industrial gateways.
With simple terminal wiring, configurable Modbus addressing, and standard communication parameters, the module is well suited for distributed temperature monitoring across cabinets, machinery, rooms, pipelines, cold storage, and industrial processes.
Its compact, centralized design reduces wiring complexity and overall system cost when compared to using multiple single-channel temperature devices.
