Integrated electronic pressure sensor reduces wiring complexity and enables real-time pressure feedback, lowering installation time while improving monitoring accuracy for automated lines and robotics cells. This enables tighter process control and quicker fault diagnosis, translating to higher uptime and consistent product quality in continuous production environments. The G1/2 inlet with Rc1/8 gauge port standardizes connections across existing pneumatics islands, simplifying retrofits and new installations alike while reducing the need for bespoke adapters. As a relieving regulator, it mitigates backpressure transients, protecting downstream actuators and extending component life in high-cycle packaging and pick-and-place applications. The push-to-lock knob features tamper-resistant design to prevent unauthorized setpoint changes, a critical safeguard in high-volume, regulated environments. Weighing just 0.79 kg with a die-cast aluminium body, the unit minimizes panel load and thermal stress while maintaining robust durability in harsh factory conditions. Flow capacity of 125 dm3/sec (265 scfm) supports demanding air demands without sacrificing stability, and the integrated sensor enables faster commissioning and easier predictive maintenance. The Excelon Plus platform also aligns with IO-Link ecosystems, enabling seamless data capture and remote diagnostics across modern automation architectures.

FAQs

Install using standard G1/2 fittings mounted on a panel or bracket. Connect the outlet to the downstream regulator line, and use the Rc1/8 gauge port for optional pressure monitoring. Ensure O-rings and seals are nitrile-compatible, tighten fittings to manufacturer torque values, and verify the maximum inlet pressure does not exceed 20 bar. The integrated sensor reduces external wiring, simplifying commissioning in new builds and retrofits.
The R84G-4GK-RME provides an adjustable outlet range from 0.3 to 10 bar (4 to 145 psi) with a maximum inlet pressure of 20 bar. It is a relieving regulator, which aids venting during pressure setpoint changes and transient events, helping to maintain downstream stability in automated lines and robotic cells.
Yes, with a flow capacity of 125 dm3/sec (265 scfm), the R84G-4GK-RME supports demanding air demands typical in packaging and robotics applications. Its relieving design, integrated sensor, and compact 167 mm height and 86 mm length help maintain performance without compromising space, making it well-suited for panel-mounted installations in tight automation environments.
Check the datasheet for exact certification values relevant to your market. Typical considerations include CE compliance for EU operations and RoHS conformity. If your process requires IP rating or SIL-related certifications, confirm the exact model variant and regional compliance in the official documentation or with the supplier before deployment.
The integrated sensor reduces wiring and simplifies wiring schematics, speeding up commissioning and diagnostics. Real-time pressure feedback enables predictive maintenance and faster issue isolation, which lowers downtime and can shorten time-to-market for automated lines. Over the life of the system, this translates to lower labor costs, fewer spare parts, and improved process stability.
