WAGO I/O System 750 XTR Passes Corrosive Gas Test per ISA S71.04 “G3”
The XTR Series' corrosion resistance to flowing mixed gases significantly broadens its application scope.
The WAGO I/O System 750 XTR has been defying extreme environmental conditions for over 10 years. The abbreviation “XTR” stands for extreme protection against climatic influences, vibrations, shocks, and overvoltages.
The system demonstrates its strengths, particularly in demanding areas such as shipbuilding, railway technology, and the energy sector.
To further expand its application area, the WAGO 750 XTR Series has now successfully passed the corrosion test with flowing mixed gases per ISA S71.04. This makes the system corrosion-resistant to the following gases:
- H2S (hydrogen sulfide)
- SO2 (sulfur dioxide)
- Cl2 (chlorine gas)
- NOx (nitrogen oxides)
The achieved corrosivity level is “G3 (Harsh).”
WAGO Brings More Power to Harsh Environments
New PFC200 Controllers and Modules for the WAGO I/O System 750 XTR
WAGO is expanding its WAGO I/O System 750 XTR, which was engineered for demanding environmental conditions, with more powerful PFC200 Controllers and several new I/O modules. The new PFC200 technology is based on a G2 hardware and features a 1 GHz Cortex A8 CPU with 512 MB RAM and 4 GB eMMC for applications requiring high computing power or large storage space. A four-channel PWM module is also available, allowing all channels to be parameterized separately. Analog inputs for current and voltage measurements with four high-resolution channels and eight-channel low-side switching digital inputs and outputs are also new.
The WAGO I/O System 750 XTR is designed for applications subjected to environmental extremes and harsh conditions. These include the energy sector, shipbuilding, offshore facilities and railway applications. The system boasts a high number of channels on a compact footprint, which saves valuable control cabinet space. The majority of the I/O modules are only 12 mm wide and offer up to 16 channels.
Your Benefits:
- The PFC200 Controller’s G2 hardware provides more processing power
- WAGO I/O System 750 XTR with new PWM module and low-side switching digital outputs
- Reliable automation technology performs well under extreme conditions

Thus it provides a simple, general, cost-effective solution for the low- and medium-voltage ranges along with easy network analysis. The module allows measurement with voltage and current sensors that meet the IEC 60044-7/8 and IEC 61869-10/11 standards. With it, existing substations can be expanded quickly and easily without extensive modifications. Integration into the flexible WAGO I/O System 750 XTR makes installation of additional devices unnecessary. Users also benefit from the features of the robust XTR system, which can withstand high vibration and shock loads, guarantees dielectric strength and EMC and can be used in a wide temperature range from −40 to +70 °C. Typical applications of the new module include distribution substations and medium-voltage connections in industrial systems.
The Benefits for You:
- Measurement of important network parameters in medium-voltage systems
- Easy integration into existing substations
- The WAGO I/O System 750 XTR for Extreme Environments

For Robust Connections in Railway Applications: WAGO I/O System 750 XTR Now with M12 Connectors
Temperature fluctuations, shocks and vibrations – automation technology for railway applications must be safe and reliable under the most extreme conditions. WAGO has streamlined its industry-proven WAGO I/O System 750 XTR for railway applications. As part of this change, both the PFC200 XTR Controllers and Modbus TCP XTR/EtherNet/IPTM XTR Fieldbus Couplers are now being upgraded for even higher performance. Leading a host of enhancements on both devices are particularly robust M12 connectors that replace previously standard RJ-45 connectors.

Secure Protection against Dirt and Moisture
“These connectors meet tough requirements – especially those found in the railway industry,” says Manfred Kühme, the 750 XTR I/O System product manager. M12 plugs have high mechanical strength and, when plugged in, are resistant to dirt and moisture. At the same time, they ensure safe and reliable contact for error-free data transmission. In contrast to RJ45 plugs, they are not only plugged in, but also screwed into the socket in a way that makes them vibration-proof. “That’s considered the more reliable connection type for the stiff, heavy ETHERNET cables used in railway applications,” explains Kühme.
Outdoor Technology Proven Many Times Over
The WAGO I/O System 750 XTR has already proven itself in many demanding outdoor applications in the railway, marine and petrochemical industries, as well as in water and wastewater treatment systems. Certifications for a variety of applications and markets, high-performance components, a small footprint and a large selection of I/O modules are among the system’s key most important benefits for offering maximum flexibility in the most challenging conditions.
The Benefits for You:
- PFC200 and couplers from the WAGO I/O System 750 XTR are implemented in the latest, most powerful generation.
- M12 connectors for maximum protection against vibration, shock and dirt
