The integrated electronic pressure sensor enables real-time monitoring and remote diagnostics, reducing unplanned downtime and supporting predictive maintenance in busy production lines. This directly improves overall equipment effectiveness (OEE) by stabilizing outlet pressure and enabling performance analytics through IO-Link-compatible interfaces. The ergonomic T-bar adjustment delivers quick, repeatable setpoints, cutting down calibration time and operator error in high-change environments while maintaining tight tolerances for consistent tooling performance. A reduced weight and compact diecast aluminium body translates to easier mounting in crowded panels and on small pneumatic stations, streamlining installation and serviceability. The regulator tolerates a wide operating temperature range (-20 to 65 °C / -4 to 149 °F) and a robust maximum inlet pressure of 20 bar, allowing seamless integration into standard plant air networks without reengineering existing piping or support structures. The G1/2 port size and Rc1/8 gauge port combination support common pneumatic hardware and instrumentation, reducing part variety and spare-parts inventory. The relieving design provides safe pressure relief and fast recovery after setpoint shifts, helping prevent system overpressure and protecting downstream components during demand spikes. In practice, the Excelon Plus series is known for modularity: compatible with a range of IO-Link masters and IO modules, enabling scalable, digital monitoring across multiple machines. This accelerates commissioning of new lines and retrofits, delivering measurable cost savings while ensuring regulatory compliance through traceable, sensor-enabled control.

FAQs
To install the R84G-4GT-RFE, connect the G1/2 inlet to the compressed air supply using a compatible gasket or thread sealant, then attach the outlet to the downstream regulator or actuator. Ensure the gauge port Rc1/8 is accessible for calibration checks. Verify air cleanliness and tighten connections to avoid leaks. After mounting, calibrate the T-bar adjustment to the desired setpoint and pair with IO-Link if monitoring is required.
The regulator provides an outlet adjustment range of 0.3 to 4 bar (approximately 4 to 58 psi) and supports a maximum inlet pressure of 20 bar. These specs enable reliable control across typical industrial pneumatic networks and tooling that require stable, adjustable pressure with relief protection during demand fluctuations.
Yes. The Excelon Plus platform supports digital monitoring options via IO-Link interfaces. When paired with suitable IO-Link masters and modules, you can capture real-time pressure data, setpoint changes, and diagnostic information, enabling predictive maintenance, remote tuning, and data-driven optimization of pneumatic circuits across automation cells.
Regularly inspect the regulator for leaks around fittings, verify that the T-bar actuator moves freely without binding, and test the outflow pressure against the setpoint with the connected load. Replace elastomeric seals if wear is detected, keep the gauge ports clean, and review IO-Link diagnostics to flag sensor drift or communication faults. Document calibration changes for compliance audits.
Expected ROI comes from reduced downtime due to integrated sensing, faster commissioning with a compact form factor, and fewer spare parts due to standardized G1/2 and Rc1/8 interfaces. The combination of precise pressure control, inline monitoring, and easier maintenance lowers energy waste, increases tool life, and shortens changeover times, delivering tangible cost savings over the regulator’s service life.
