Dynamic Electro-Hydraulic Servo Controller
Features of OD1200
• 2-channel digital controller
• Digital loop cycle rate: 4 kHz
• 16-bit resolution
• Supports independent feedback source for each control loop
• Manual PID tuning
Amplitude Control (Optional)
• Multiple outputs available to control mean value and amplitude, simplifying control for low-load & large-displacement tests
• Dual-loop / dual-setup mode (Optional)
• Dual-loop technology: inner and outer control loops with separate feedback signals (e.g., force for inner loop, displacement for outer loop)
• Inner loop limit protection (to avoid invalid setpoints from the outer loop)
Function Generator
• Frequency range: 0.1 Hz ~ 200 Hz
• Waveforms: sine wave, square wave, triangular wave, dual-sine wave, etc.
• External signal input
Analyzer Generator (Optional)
• Arbitrary waveform generation
• Cyclic test sequencing
• Actions: enable/disable, pressure switch trigger, digital input wait, static setpoint, range configuration, amplitude control enable/disable, etc.
Servo Valve Drive
• Two configurable output modes: 50 mA current output or ±10 V voltage output
• Dither signal: 0–25% amplitude, frequency range 15–1000 Hz
Hydraulic Control
• Relay switch output: 1 A, 24 VDC
• Status / pump interlock logic
• Standard industrial M12 connectors
• High/low pressure control via 1 A, 24 VDC relays
Signal Conditioning
• Configurable via jumpers and software (gain, offset, balance, shunt calibration)
• Compatible with AC/DC LVDTs and resistive bridge sensors
• Inputs for 2 DC resistive bridge sensors
• Built-in calibration function
• Dual encoder input channels
Limit Protection
• Min & max threshold limits
• Instantaneous deviation, amplitude and mean value error limits
• Configurable protective actions when limits are triggered
Power Supply
• 90–240 VAC, 47–63 Hz
