IL100 Series 1:1 Precision Booster Relay (Pneumatic Amplifier)

Brand: SOLH by Richge Technology 

Product Positioning

     IL100 series is a 1:1 precision booster relay fully interchangeable with SMC original models, also known as pneumatic signal amplifier or volume booster. Its core function is to convert low-flow control signals into equal-pressure high-flow air output. It effectively solves slow response issues caused by long piping runs and large-volume pneumatic actuators, featuring outstanding precision, ultra-large flow capacity and ultra-fast response speed.

 Core Function & Working Principle

  1. Fundamental Definition

       Pneumatic signal & volume amplifier with precise 1:1 pressure tracking (output pressure strictly equals input signal pressure).

  2. Operation Logic

     --SIG (Signal Port): Receives low-flow control pressure output from positioners or pressure regulators

     --SUP (Supply Port): Connect to main compressed air supply, max supply pressure 1.0 MPa

     --OUT (Output Port): Delivers high-flow air at identical pressure to drive large actuators

     --EXH (Exhaust Port): Rapidly exhausts residual air when control signal pressure drops

  3. Core Value

     Maintain exact signal pressure while amplifying output flow, drastically speeding up actuator movement.

Core Key Features

   1. Ultra-High Flow & Instant Response

     -- Max flow capacity: 6,000 L/min (ANR) under 0.7 MPa supply pressure
