IF-96005: Alarms Interface for Nemo 96HD/HD+ Series

The IF-96005 module, when combined with meters from the Nemo 96HD/HD+ series, allows the monitoring of electrical quantities through 2 independent and insulated alarms. Each meter (Nemo 96HD/HD+) can accommodate a maximum of two IF-96005 modules, enabling the configuration of up to four alarms.

Programmable Parameters for Each Alarm:

• Associated Quantity:
  • 3n3E: 3-phase 4-wire line, 3 systems.
  • 3-3E: 3-phase 3-wire line, 3 systems.
  • 3-2E: 3-phase 3-wire line, 2 Aron systems.
  • 1n1E: Single-phase line.
  • U1-U2-U3: Phase voltage.
  • U12-U23-U31: Linked voltage.
  • A1-A2-A3: Phase current.
  • P1-P2-P3: Phase active power.
  • P: 3-phase active power (single-phase for 1n1E connection).
  • PM: Active power demand.
  • VAr1-VAr2-VAr3: Phase reactive power.
  • VAr: 3-phase reactive power (single-phase for 1n1E connection).
  • VArM: Reactive power demand.
  • PF: Power factor.
  • FrEq: Frequency.
  • tMP1-tMP21: Temperature (with IF96016 module).
• Intervention Threshold: Point of intervention.
• Type of Alarm: Minimum or maximum.
• Relay State: Normally energized or de-energized.
• Hysteresis: 0 to 20%.
• Intervention Delay: 0 to 99 seconds.
• Reset Delay: 0 to 99 seconds.

Output:

• Relays: 2 potential-free SPST contact relays.
• Contact Rating: 5A at 250V AC (cosϕ 1), 3A at 250V AC (cosϕ 0.4), 5A at 30V DC.

Auxiliary Supply:

• Rated Burden:
  • IF-96005: ≤ 1VA.
  • Nemo 96HD/HD+ with IF-96005: ≤ 5VA.
  • Nemo 96HD/HD+ with 2 IF-96005 interfaces: ≤ 6VA.

Insulation (EN61010):

• A.C. voltage test: 2 kV (r.m.s.) value at 50Hz for 1 minute.
• Considered Circuits: Measurement input, auxiliary power, output 1, output 2.

Housing:

• Type: Module with a connector for the Nemo 96HD/HD+.
• Maximum Depth: 81mm (with module).
• Connections: Screw terminals.
• Terminal Range:
  • Rigid cable: max. 4.5mm².
  • Flexible cable: max. 2.4mm².
