Product Description
The HD35EDWH is a versatile wireless data logger designed for outdoor and industrial monitoring applications, featuring 4 configurable universal inputs in a rugged IP67 waterproof housing.
Each input can be independently configured for a wide range of sensor and signal types, including Pt100/Pt1000, thermocouples, 0/4–20 mA, 0–50 mV, 0–1 V, 0–10 V, potentiometers, and pulse inputs. This flexibility allows the HD35EDWH to interface with many types of industrial and environmental sensors using a single platform.
The logger stores measurements in its internal memory and wirelessly transmits the data to an HD35 base unit at configurable intervals. Its robust wireless architecture eliminates long signal cables, simplifying installation in distributed monitoring systems.
Designed for demanding environments, the HD35EDWH combines long battery life, optional external power supply, and reliable RF communication, making it ideal for industrial automation, environmental monitoring, utilities, and process monitoring applications.
