Wilkerson ER1-04-0A00 Electronic Air Regulator 150 Psi

Product Description

The WILKERSON ER1-04-0A00 is an electronic compressed air regulator designed for precise, signal-driven pressure control in industrial pneumatic systems. It accepts a 4 to 20 mA control signal and delivers regulated output pressure from 0 to 125 psi against a maximum supply pressure of 150 psi. The regulator handles flow rates up to 200 CFM, making it suitable for demanding process and automation applications. Built from aluminum, it connects via a 1/2 inch NPT port and includes an integrated relief function for downstream pressure management. Licensed instrumentation technicians and industrial pneumatic specialists are the typical installers.

This regulator is used in facilities where automated or remotely controlled pressure regulation is required. Typical applications include process automation, pneumatic control panels, and systems where a PLC or controller outputs a 4 to 20 mA signal to govern downstream air pressure. The 200 CFM flow capacity supports high-demand pneumatic circuits in both light industrial and heavier production environments. It is rated for compressed air service with a minimum operating temperature of 32 degrees F.

Key Features

• 4 to 20 mA control signal input for automated, proportional pressure regulation
• Output pressure range of 0 to 125 psi with 150 psi maximum supply pressure
• 200 CFM rated flow capacity for high-demand pneumatic circuits
• Integrated relief function to vent excess downstream pressure
• 1/2 inch NPT port for standard industrial pneumatic plumbing
• Aluminum body construction for lightweight, corrosion-resistant service

Compatibility

Designed as an OEM-style electronic regulator for industrial compressed air systems requiring 4 to 20 mA proportional control with 1/2 inch NPT connections.

Installation Notes

Installation should be performed by a qualified instrumentation technician or industrial pneumatic specialist familiar with signal wiring and pneumatic system safety. Depressurize and lock out the air supply before installing or removing the regulator. Verify the control signal source is within the 4 to 20 mA specification before energizing the control loop. Follow applicable OSHA and facility safety procedures for compressed air systems during commissioning.
