The Setpoint Interface is a control component integrated into Pressure Regulation Modules that allows operators to input, modify, and monitor the target pressure setpoint. It serves as the human-machine interface for configuring the module's operational parameters, typically featuring input mechanisms (buttons, dials, touchscreens) and display elements to show current and target values. The interface converts user input into electrical signals that communicate the desired setpoint to the module's control system, which then adjusts the pressure accordingly. It includes signal conditioning, validation logic, and feedback mechanisms to ensure accurate parameter transmission. The interface is designed for use in industrial environments, with materials including engineering plastic, stainless steel, and electronic components. Key parameters include an operating pressure range of 1.0–1.6 MPa, setpoint accuracy of ±0.5% of span (including hysteresis and repeatability), adjustment range of 10–100% of full scale (full scale 1.6 MPa), supply voltage of 24 V DC ±10% (reverse polarity protected), current consumption ≤50 mA at 24 V DC without load, output signal of 4–20 mA (two-wire, loop powered), operating temperature of -40–85 °C for electronics (media temperature may differ), media temperature of -20–120 °C for water, oil, and air, ingress protection of IP65–IP67 (depending on housing and cable gland, per IEC 60529), process connection of G1/4–G1/2 female thread (other sizes on request, per ISO 228-1), wetted materials of 316L stainless steel (optional Hastelloy C276, per ASTM A276), and weight of 0.8–1.2 kg depending on connection size and options. These values are reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. The interface is a component, not a standalone device, and its performance is integral to the pressure regulation module.
The Setpoint Interface converts user input (manual adjustments or digital commands) into electrical signals that communicate the desired pressure setpoint to the module's control system. It includes signal conditioning, validation logic, and feedback mechanisms to ensure accurate parameter transmission. The interface may feature buttons, dials, or touchscreens for input, and displays for showing current and target values. The electrical signals are typically analog (4–20 mA) or digital, and the interface is powered by a 24 V DC supply. The control system uses these signals to adjust the pressure regulation mechanism accordingly.
