HV DTemp-Mx Controller
Controller for addressing and power supply of IC sensors
The M-series controller was developed for the connection of IC sensors. The HV DTemp-M Controller provides the addressing, the power supply of the sensors and the transmission of the measurement values to the HV DTemp-P Central Unit.
Highlights
- Control and bundling of up to 64 measurement points (per controller)
- Cascading of up to eight controllers (for a maximum of 512 temperature or humidity measurement points)
- Measurement data rate / sending rate: 1, 2, 5, 10, 20 Hz
- Different design for individual adaptation of the measurement setup
Description
The HV DTemp-Mx controllers provide the connection between HV DTemp IC sensors and HV DTemp-P Central Unit. For this purpose they have the following connection options:
- Controllers have eight or 16 port inputs.
- Up to four IC sensors can be connected per port. This results in up to 64 measurement points per controller.
- For convenient connection, the IC sensors are connected to the ports of the controller via sensor connection cables.
- Up to eight Mx controllers can be cascaded.
- All controllers are connected to the central unit (outside the HV environment) via a single HV-safe cable.
The HV DTemp-Mx controllers are available with different isolation. Thus, depending on the requirements of the measurement task, the appropriate controller can be selected regarding to the required number of ports and the desired isolation.

Applications
A large number of IC sensors can be addressed and supplied with voltage within the HV battery using just a few controllers. This measurement setup ensures that only one HV-safe cable is required for up to 512 measurement points.
The different variants of the controllers allow an individual adaptation of the measurement setup to the respective requirements of the measurement task. With their compact design, the HV DTemp controllers can be easily installed inside the battery.
The HV DTemp measurement system is suitable for all demanding temperature and humidity measurements with a large number of sensors in confined installation spaces. The measurement system can be used to determine temperature profiles between the battery cells, especially in HV batteries, e.g. for the optimization and validation of HV batteries in electric or hybrid vehicles.
