Foxboro FBMSVH Control Card New Arrival In Stock

Overview:

The Foxboro FBMSVH control card is designed for closed-loop control systems to precisely control the position of pneumatic or hydraulic servos. It accepts input commands within the range of 4-20mA or 0-10VDC, and feedback input can be derived from an LVDT with a 0-10V signal. After processing the DEH command and LVDT feedback voltage using P or P+I regulation, it outputs a ±27mA current to drive the servo valve. The module operates with an external ±15V power supply, which can be connected to the respective input terminals.

Key Features:

• Selectable current or voltage input (DEH) with separately adjustable zero point and full-scale range using the S2 switch.
• Equipped with an LVDT modulator and demodulator with adjustable amplitude and a driving current of 50mA.
• Capable of outputting a 0-20mA valve position signal with an impedance of 50Ω.
• Allows for external shutdown contacts and adjustable proportional and integral control loops.
