The Mitsubishi MR-J4-22KA4 is a 2.2 kW (3.0 HP) servo amplifier from the MR-J4 series, designed for high-performance motion control in industrial automation. It supports absolute/incrmental encoders and is compatible with HG-KN/HG-SN servo motors, offering ultra-high precision positioning, fast response, and energy efficiency.

The ABB PM803F Base Unit 16 MB is an essential component in industrial automation systems, offering advanced control solutions with high-performance computing and scalable memory.

Key Parameters Category Parameter Name Description & Typical Values General Specifications Actuator Type Pneumatic, Spring-Return (Single-Acting) Motion Linear (sliding-stem) Diaphragm Case Material Carbon Steel (Standard), Stainless Steel optional. Spring Housing (Yoke) Cast Iron or Carbon Steel. Air & Pressure Data Standard Supply Pressure 3-15 psig (0.2-1.0 bar) control signal. Maximum Supply Pressure Typically 50 psig (3.4 bar) for most sizes, but can be higher for specific configurations. Diaphragm Size Large diameters, e.g., 450 sq. in., 850 sq. in., etc., to generate high force. Thrust Output Stem Thrust Generates very high thrust. Specific values are defined by thrust charts based on air supply pressure, diaphragm size, and effective spring rate. • Example: A large Type 99 can produce thrust exceeding 50,000 lbs (222 kN). Spring Ranges Multiple spring ranges are available, defined by their spring rate (e.g., lbs per inch of travel). Performance & Physical Stroke Lengths Available in various standard stroke lengths (e.g., 1.5", 2", 3", 4", 6"). Action Air-to-Open (Fail Close) or Air-to-Close (Fail Open) - Field-reversible. Temperature Limits Standard: -20°F to 150°F (-29°C to 66°C). High-temperature kits available for up to 250°F (121°C).
