Description
IF-96006: Neutral Current Interface for Nemo 96HD/HD+ Series
The IF-96006 module, used in conjunction with Nemo 96HD/HD+ series meters, allows for the measurement of neutral current (typically calculated by the meter).
Features:
- Input:
- Suitable for single-phase and three-phase 4-wire networks.
- Direct connection (max. 5A) or through an external dedicated current transformer (CT).
- Current ratings: 5A – 1A.
- Frequency rating: 50Hz (allowed variation: 47…63Hz).
- Measurement type: True RMS value.
- Harmonic content measurement: Up to the 22nd harmonic.
- Rated burden: ≤ 0.5 VA.
Programmable Parameters:
- External CT Ratio: 1…9999.
- Programming of the neutral CT ratio is completely independent of the measuring CTs connected on phases L1, L2, and L3. This allows the neutral CT to differ from the measuring CTs in terms of ratio and secondary.
Auxiliary Supply:
- Consumption: ≤ 5VA for the combined Nemo 96HD/HD+ multifunction meters and IF96006 interface.
Insulation (EN61010):
- A.C. voltage test: 2kV r.m.s., 50Hz for 1 minute.
- Considered circuits: Measurement input and auxiliary supply.
Housing:
- Type: Module with a connector for the Nemo 96HD/HD+ meter.
- Maximum Depth: 81mm (includes both the meter and module).
- Connections: Screw terminals.
- Terminal Capacity:
- Rigid cable max. 4.5mm².
- Flexible cable max. 2.5mm².
- Material: Self-extinguishing polycarbonate.
- Weight: 50 grams.
Firmware Version:
- 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 IF96001 (RS485) or IF96002 (RS232) communication module, along with a PC and the necessary software.
