The Zone1 Ethernet gateway for the excom I/O system enables data-based monitoring and process optimization in existing plants
Intrinsically Safe Ethernet Gateway for Zone 1
17/25 – With the GEN-2G gateway for its excom I/O system, TURCK is the first manufacturer to bring intrinsically safe, copper-based Ethernet to ATEX Zone 1
Mülheim, November 13, 2025TURCK presents a new solution for Ethernet communication in hazardous areas. The GEN-2G multiprotocol gateway enables a continuous, intrinsically safe, copper-based Ethernet infrastructure in ATEX Zone 1 for the first time. The new solution expands the existing excom system with the GEN-3G Zone 2 gateway, now allowing easy conversion from Profibus DP to Ethernet communication in Zone 1 as well – without replacing the I/O and sensor level.
Communication between non-hazardous and hazardous areas is carried out using fiber optic cables with TURCK's FOCEN11Ex-2G and FOCEN11-3G media converters – over distances of up to 2,500 m. From this point, several excom stations can be integrated intrinsically safely via copper cables in Zone 1. This eliminates the previously common, costly point-to-point installation of each station via fiber optic cable. The GEN-2G multiprotocol gateway even allows hot swapping during operation without the need for a fire extinguisher. With the GEN-2G, existing excom installations can also be quickly and cost-effectively converted to Ethernet communication and made future-proof.
International approvals such as ATEX, IECEx, CCC, and others, as well as maritime approvals (DNV, BV, LR, ABS, KR) expand the system's range of applications. The solution enables easy connection of sensors and actuators as well as the integration of HART data for diagnostics and IIoT applications. Since the entire excom family has system approval for hazardous areas, extensions do not need to be re-approved; this can be done by the user.
