Autonomous IIoT telemetry module
VADTel-AIIoTU8
Battery-powered cellular telemetry module for gas volume correctors in hazardous areas — 8,000 mAh Li-ion, no external power supply needed.
-
Autonomous power
An 8,000 mAh Li-ion battery powers the module — no external supply needed at the metering node.
-
Intrinsically safe link
The integrated Ex ib barrier lets the RS-485 line reach gas volume correctors in Zone 1 (Ex version).
-
Cellular-first
Reports to the Data Platform over GSM, GPRS, LTE-M or NB-IoT, with GSM 850–1900 MHz and LTE-M B1/B3/B8/B20 bands.
VADTel-AIIoTU8 is the autonomous member of the VADTel telemetry family: corrector telemetry like VADTel-IIoTU3, but on its own 8,000 mAh battery for metering nodes without an external power supply. The “A” in the name stands for autonomous.
The module provides remote telemetry for gas volume correctors, heat calculators and water meters and transfers their readings to the Data Platform over cellular networks.
