8-Channel Digital Temperature Acquisition Module

The 8-channel digital temperature acquisition module from Kingmach is built for monitoring situations where you need consistent, time-synchronized temperature data from several sensors. Each channel connects independently, so you can space sensors meters apart or bunch them for high-resolution profiling. The module uses a 24-bit ADC for each channel, which provides fine resolution without range switching—common in moderate-speed temperature logging. Digital filtering on board helps knock down 50/60 Hz noise from nearby power lines, a frequent headache in industrial environments. Output is over RS485 with standard Modbus RTU protocol; registers hold raw ADC counts or temperature values in engineering units, selectable via configuration software. The module operates from a wide DC supply range (typically 9-30 V), making it convenient for solar-powered remote stations. Kingmach includes basic calibration in the factory, and for projects that require traceability, they can supply calibration certificates from an accredited lab. The aluminum enclosure is rated IP65 for dust and water jets, so it survives in unheated instrument huts or attached to a mast. If your site has specific needs—like an extended temperature range, different sensor excitation, or POE connectivity—Kingmach’s engineering team can work out a variant from their existing platform. They maintain a global network of distributors, which means getting units into the field and receiving local support is usually straightforward. Applications range from geothermal gradient measurement, to concrete mass pours, to leachate temperature monitoring in landfills. The module’s ability to deliver synchronized multi-point data helps engineers spot thermal trends earlier and with more confidence than relying on separate standalone loggers.
