High-Density Aggregation
A single concentrator easily manages all sensors across multiple switchgear lineups or an entire outdoor substation bay.
Heavy-duty industrial data concentrator purpose-built for substation automation and switchgear monitoring. Collects thermal telemetry from more than 1,000 wireless VTI-TS sensors, seamlessly connecting to SCADA, DCS and Cloud via Modbus TCP, MQTT over TLS and IEC 60870-5-104.
Industrial Gateway GW22 DIN-rail mounted in substation auxiliary protection cubicle
The GW22 (and dual-band GW22-D) is a DIN-rail or panel-mounted industrial data concentrator engineered to aggregate wireless telemetry from more than 1,000 VTI-TS sensors across substation switchyards and switchgear panels. It operates in a passive, receive-only listening hub mode, generating zero high-power RF emissions that could perturb digital protection relays.
Out of the box, the concentrator supports native industrial protocols: Modbus TCP, MQTT over TLS and IEC 60870-5-104 for direct SCADA/DMS ingestion. IEC 61850 compatibility is in the active product development roadmap.
Designed specifically for high-electromagnetic interference substation environments.
A single concentrator easily manages all sensors across multiple switchgear lineups or an entire outdoor substation bay.
GW22-D concurrently receives short-range BLE from enclosed switchgear cubicles and long-range LoRa (up to 3 km) from outdoor switchyards.
Directly outputs temperature telemetry, phase ΔT differentials and alarms via Modbus TCP, MQTT over TLS and IEC 60870-5-104.
Receive-only architecture guarantees complete electromagnetic compatibility (EMC), ensuring total safety near digital protection IEDs.
Wide-range power supply connects directly to substation 110–220 V DC station battery banks or 220 V AC utility lines.
Measuring 93 × 84 × 24 mm and weighing 200 g, it mounts effortlessly into switchgear low-voltage control compartments.
