Description
Product Overview
The TRO620 is a DIN-rail mount utility-grade industrial communication router originally from Tropos, now under Hitachi Energy. It combines 4G/LTE cellular modem, Gigabit Ethernet ports, serial interfaces and 802.11 broadband mesh radio for field area networks (FAN). It is designed for substation automation, distribution SCADA, oil & gas remote sites, mining and critical infrastructure to connect IEDs, PLCs and RTUs over wireless private/public cellular networks, supporting edge computing and secure remote monitoring.

Key Features
- Dual communication architecture: cellular wide-area link plus local wireless mesh backhaul for redundant field connectivity.
- Multiple Gigabit Ethernet and serial ports to mix modern IEDs and legacy serial automation equipment.
- Hardware TPM 2.0 crypto engine for critical infrastructure cybersecurity, supporting secure key storage and device authentication.
- Edge-compute ready, runs Hitachi SuprOS; enables local data processing and autonomous operation when cellular link drops.
- Industrial wide-temperature design, shock and vibration rated for outdoor cabinet and substation environments.
- Over-the-air dual-image firmware upgrade; supports rollback if new firmware fails, reducing site maintenance risk.
- Central network supervision via SuprOS platform for router health, alarms and configuration management across large fleets.
Installation & Testing Notes
- Mount on standard DIN rail inside NEMA / IP rated substation enclosure, ensure proper heat dissipation.
- Use surge protection on DC power, Ethernet and antenna feeders for lightning-prone substation sites.
- Install cellular and mesh antennas with proper cable loss calculation; keep antenna ground separation for isolation.
- Configure firewall rules, VPN tunnels and device certificates before connecting to SCADA network.
- Test cellular signal strength, mesh link stability and end-to-end Modbus/DNP3/IEC61850 communications.
- Validate OTA firmware update and rollback function during commissioning.
- Inspect power terminal block, antenna connectors and Ethernet ports for corrosion or pin damage before spare deployment.
FAQ
Q: What is TRO620 used for? A: It is a utility field router for remote SCADA and substation automation, combining cellular and wireless mesh for field area networks.
Q: Does TRO620 support IEC 61850? A: Yes, it supports IEC 61850 MMS/GOOSE pass-through for substation IED communication.
Q: Is TRO620 the same as ICS Triplex T-series SIS module? A: No. TRO620 is a Hitachi Energy communication router, not a Trusted TMR safety module.
