Product Information

Full details

The Finder 7M.24.8.230.0001 is a compact, DIN-rail mounted, single-phase energy meter ideal for private or non-commercial applications needing precise energy consumption monitoring. Its key benefit is providing clear, reliable energy usage data via a digital LCD display and an S0 pulse output for remote tracking. A primary caveat is that it is not MID certified, making it unsuitable for billing purposes in many commercial scenarios.

FAQs

What is the primary use case for this energy meter?

This meter is designed for monitoring energy consumption in private or non-commercial applications, such as domestic settings, small businesses, or for tracking specific circuits, rather than for official electricity billing.

Is this meter MID approved?

No, the Finder 7M.24.8.230.0001 is not MID certified, which means it cannot be legally used for billing purposes in most European countries.

How do I connect the S0 pulse output?

The S0 pulse output consists of two terminals. Connect these to your data logger or monitoring system according to the system's input requirements. The meter provides 1000 pulses per kWh consumed.

What is the maximum current this meter can handle?

The meter has a nominal current (In) of 5A and a maximum current (Imax) of 40A. It also has a short-term overload capacity of 1200A for 10ms.

Can this meter be used for multi-phase systems?

No, this is specifically a single-phase energy meter designed for L-N connections.

What is the accuracy class of this meter?

This energy meter has an accuracy class of B for active energy measurement.

Does the meter require an external power source to operate?

The meter is powered by the 230V AC supply passing through it. No separate power supply is needed for its operation.

Troubleshooting

Display is blank or not showing readings.

Verify that the power supply (230V AC) is correctly connected to the line (L) and neutral (N) terminals. Ensure the circuit breaker for that line is switched on.

Meter seems to be running backward or showing negative consumption.

Check the line and neutral connections. The meter is directional; ensure power flows from the input terminals to the output terminals as expected.

S0 pulse output is not sending signals.

Confirm that the S0 output terminals are correctly wired to your monitoring device. Ensure the connected device is configured to receive S0 pulses and check the compatibility of the pulse rate (1000 Imp/kWh).

Inaccurate readings.

Ensure the meter is correctly rated for the connected load (up to 40A). Verify that no unauthorized modifications have been made and that the meter is within its operational temperature range.

Pros and Cons

Pros

  • Compact and space-saving DIN-rail design
  • Clear LCD display for easy data reading
  • S0 pulse output for remote monitoring capabilities
  • Suitable for private and non-commercial monitoring
  • Direct connection simplifies installation for its rating

Cons

  • Not MID certified, limiting use for billing
  • Limited to single-phase systems
  • Maximum current rating of 40A may not suit all applications
  • External tariff control required for tariff switching

Setup, Compatibility & Care

Setup:

This meter is designed for DIN-rail mounting. Ensure the power supply to the circuit is switched off before installation. Connect the line and neutral conductors to the appropriate terminals as indicated on the device. The S0 pulse output terminals should be wired to your data logging or monitoring system.

Compatibility:

  • Voltage: Compatible with standard 230V AC single-phase (L-N) systems.
  • Frequency: Operates on 50-60Hz.
  • Current: Suitable for circuits with a nominal current of up to 5A and a maximum of 40A.
  • S0 Interface: Compatible with systems that accept S0 pulse inputs (e.g., PLCs, data loggers, certain smart home hubs). Check the pulse rate (1000 Imp/kWh) against your receiving device's specifications.
  • Environment: Operates within an ambient temperature range of -25 to +55 degrees Celsius.

Care:

  • Cleaning: The meter casing can be cleaned with a dry or slightly damp cloth. Do not use solvents or abrasive cleaners.
  • Environment: Ensure the meter is installed in a location protected from excessive dust, moisture, and direct sunlight, adhering to its IP20 rating. The terminal shield is sealable for added protection against tampering.
