Features

Uses a LCD
The display screen features a LCD that is 5-times larger than the screens of previous models for enhanced visibility.
TemTripPRO
This also allows device states to be checked visually
TemTripPRO
Easy wiring
All input and output terminals use connectors as the connection method, making wiring much easier than previous models.
Includes arc detection function (optional)
Arcing due to internal short circuits, circuit breaks or other causes are detected with an optical device to trigger an output. This allows issues that cannot be detected with currents or voltages to be identified much faster.
Includes communication function (optional)
The communications function allows for transmission and centralized management of measured values or historical data. Modbus RTU is used as the communications protocol for easier system development.
