IF-96012: RS485 Interface for Nemo 96HD/HD+/HDLe Series

The IF-96012 module, used in conjunctions with Nemo 96HD/HD+/HDLe series, allows all the data relevant to measurements and configuration parameters to be retrieved via an RS485 Interface. Thanks to its internal memory, it stores energy counts and main measured parameters.

Memory

Measurements are saved in a sliding-window memory, where the oldest data is overwritten by the newest. The memory allows reading previous data, with a time depth that varies depending on the saved data quantity and the saving interval.

Programmable Parameters – Memory

• Clock: hour, minutes, seconds
• Date: day, month, year
• Daylight saving time: start and end date and time
• Time interval between data backups: 2-5-10-30-60 seconds – 2-5-10 minutes
• Saved data: type 0/1/2/3
• Reset saved data

Firmware Version:

The table indicates compatible meters for the IF96012 module, along with position constraints and the maximum number of modules usable. It also shows the firmware version of the meter necessary to support the additional module’s function.

The firmware version of the meter required to support the module’s function is indicated in the documentation. Firmware can be updated in the field using an IF-96001 (RS485) or IF-96002 (RS232), or IF-96015 (Ethernet) communication module, along with a PC and the necessary software.
