SENSECOM-IMNT

Remote impulse readings with data transmission via nationwide LPWAN IoT network 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 direction of the medium flow using the DIR input.
  • DIR – voltage-free* input used to differentiate the direction of flow of the medium
  • DI – Voltage-free* digital input (without galvanic isolation), used e.g. for intrusion or flood detection.
• Secondary voltage-free input
  • reading from a gas meter / water meter equipped with a voltage-free contact
  • suitable to use IMNB model with several hours backup for mains power failure
• 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 ISM 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.
