ALTA Industrial Wireless Voltage Detection


ALTA Industrial Wireless Voltage Detection - 200 VDC

Part #:MNS2-8-IN-VD-DC-200

Frequency:868 MHz (Euro)

Battery: 10 years

Range: 360 metres



Product Description

The ALTA Industrial Voltage Detector – 200 VDC detects the presence or absence of electricity. It is intended for use on battery or other DC sources, up to 200 Volts. Not intended for use with AC Voltages. It is perfect for batteries, adapters, solar equipment, vehicles or machinery, and any other electrical appliance monitoring. The sensor triggers on voltage presence to voltage Absence and vice versa. The data is displayed as “Voltage Detected” or “No Voltage”.


ALTA – Leading Enterprise Grade “Internet of Things” Solutions

ALTA sensors offer 3 to 4 times the range of standard sensor platforms, extending non-line-of-sight reach to an exceptional 1,000+ feet through walls (12-14 walls typical). Using Frequency-hopping Spread Spectrum (FHSS) also allows ALTA sensors to have better interference immunity from other wireless devices.

Superior power management provides ALTA sensors with almost twice the battery life of Monnit’s standard wireless sensors.

  – Coin cell sensors typically last 3+ years.

  – AA and Industrial sensors typically last up to 10+ years.


ALTA products employ Monnit’s new Encrypt-RF™ Security (256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages), so security is maintained at all communication points from sensor to gateway, gateway to software, then back again.


Integrated on-board data storage allows ALTA sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range). Messages that can’t be delivered will be time-stamped and stored in memory (up to the last 3100 messages) until communication with the gateway is restored, at which point the messages will all be transmitted.


Over-the-air updates allow ALTA products to be updated remotely if new fixes or features become available.

Monnit ALTA Industrial Sensors come in an IP65, NEMA 4X, CE rated, sealed, and weatherproof enclosure. They are powered by a single, replaceable, Industrial grade 3.6 V battery (included).


An optional solar powered version is also available. The solar powered version includes a Lithium Iron Phosphate rechargeable battery in conjunction with a solar power cell to keep the battery charged and at optimal capacity. If there is no light present at the solar cell, the battery alone could continue to power the sensor for up to 8-10 years.


  – Interfaces with other devices or power lines up to 200 volts DC.
  – Max sensor input voltage up to 200 volts DC.


 * Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
