How TG452B Works in Your IIoT System

TG452B collects raw signals from field devices, executes local edge logic, stores data locally on TF‑card, then forwards standardized data to on‑premise SCADA or Bivocom DMP / third‑party cloud platforms via cellular / Ethernet / Wi‑Fi uplink.

Backup battery ensures continuity during power blackouts.
