Features
· Adaptive predictive control algorithm for faster response and more precise control.
· Automatic detection of valve lower and upper limits, opti mizing valve control parameters to enhance accuracy.
· Dot matrix LCD display with multi-language support, ro tatable by 180° for easy observation. Equipped with four configuration buttons for local valve control and settings adjustments.
· Supporting parameter configuration for split range, characteristic curves, stroke range and direction, tight closure, dead zone, control parameters, digital input, alarm and fault outputs, and more.
· Diagnostic capabilities include leakage detection, partial stroke testing, upper and lower limit monitoring, pressure and temperature diagnostics, stroke accumulation, directional change counts, and piezoelectric operation monitoring.
· IDM software allows setup and calibration of valve accessories, with status monitoring and alarm tracking.
· Compatible with HART 5 and HART 7 communica tion protocols.
· Including one isolated digital input and two dry con tact inputs.
· Digital output with electric isolation provides alarm or fault notifications.
· Electrically isolated position feedback block outputs 4 to 20mA position feedback.
· Optional "faillast" function ensures operational stability during power, gas, or signal failure.
· Equipped with surge protection for enhanced reliability.
