Remote impulse readings with data transmission via nationwide NB-IoT
- Remote consumption reading of electricity, water, gas, etc. based on pulse sensors
- Primary input –
- CNT0, CNT1 – voltage-free* inputs for pulse meter readings.
- The CNT0 input can split the pulses into 2 counters according to the medium flow direction.
- DIR – voltage-free* input used to differentiate the medium flow direction
- DI – Voltage-free* digital input (without galvanic isolation), used e.g. for intrusion or flood detection.
- CNT0, CNT1 – voltage-free* inputs for pulse meter readings.
- Secondary voltage-free input
- reading from a gas meter / water meter equipped with a voltage-free contact*
- Power supply
- lithium battery size “C” (type SAFT LS 14 3.6 V, 5.8 Ah).
- Life >10 years at 1h readings with 12h message period
- outdoor design, IP67
- Models:
- IMNT – 1x M12 grommet
- IMNT2 – 2x M12 grommet
- External NB antenna via SMA connector
- Broadcasting to the NB-IoT nationwide network
- Optional E2E encryption using AES256
*Alternatively open collector output limited to max. 0.5 V at max. 0.5 mA in closed state. The input is not galvanically isolated (n/a for battery models)
