Digi TX65 Brings Rugged 5G Connectivity to PLC-Driven Industrial Sites

Detail

The TX65 family spans three configurations, all built around a 5G Release 17 modem and sharing a common ruggedized DNA. The base TX65-5B-1N pairs a single 5G modem with one Wi-Fi 7 radio. The TX65-5B-2N upgrades to dual concurrent Wi-Fi 7 radios for passenger and operational traffic segregation. At the top, the TX65-5B5A-2N runs dual 5G modems across eight cellular antennas for multi-carrier resiliency , a feature automation engineers will recognize as essential for failover in remote SCADA backhaul scenarios.

Every model operates from -40°C to +75°C with IP64 ingress protection and accepts 9, 36 VDC vehicle power, making direct integration into industrial control cabinets feasible without additional power conditioning. Wired connectivity includes one 2.5 GbE WAN port and four 1 GbE LAN ports, sufficient for daisy-chaining PLCs, HMIs, and local IIoT gateways.

The industrial routers market is projected to climb from USD 3.08 billion in 2025 to USD 4.59 billion by 2031, a CAGR of 6.88%. Within that, the 5G connectivity segment , still at roughly 8.7% market share in 2025 , is forecast to expand at a blistering 27.3% CAGR through 2034. Digi's TX65 launch positions the company to capture early-mover advantage as 4G LTE replacements accelerate across brownfield industrial sites.

The TX65 arrives at a moment when the IT/OT convergence market is racing toward a combined value exceeding USD 1 trillion by 2030. For system integrators, the router's dual-modem architecture means production data from PLCs and telemetry from auxiliary sensors can traverse separate carrier networks simultaneously , a practical answer to the long-standing challenge of converging operational technology traffic with enterprise IT infrastructure without compromising either.

Digi Remote Manager, included as part of the Digi 360 package, provides centralized configuration, firmware management, and security monitoring across distributed TX65 fleets. For automation teams managing hundreds of remote PLC cabinets, this eliminates the truck-roll burden traditionally associated with router maintenance at unmanned sites.

FIPS 140-3 validation , mandatory for U.S. federal agencies, defense contractors, and critical infrastructure operators , is baked into the TX65 cryptographic modules. This matters acutely in water treatment, energy distribution, and transportation sectors, where PLC-driven processes intersect with regulatory compliance frameworks. The eSIM and dual-SIM failover capabilities further harden the connectivity layer by enabling carrier-agnostic fallback without physical SIM swaps at remote locations.

The combination of GNSS location services, Wi-Fi 7 tri-band support, and 5G Release 17 compatibility makes the TX65 one of the few industrial routers capable of supporting both high-bandwidth predictive maintenance analytics and low-latency control traffic on a single platform. Early adopters in distributed manufacturing and pipeline monitoring are expected to lead uptake.
