The VC2124 voltage-to-current converter transforms ±10V signals into current signals capable of driving hydraulic servo valves or similar loads. It also provides a convenient way to set the full scale current to match valve requirements, limit maximum current, or set optimum working ranges.

Features

• Two channels of voltage-to-current conversion
• Full scale output current switch-selectable from ±10mA to ±100mA in 10mA steps (each channel set independently)
• Inputs and outputs can be paralleled for output current up to ±200mA
• Dual-color LEDs indicate input polarity and amplitude
• LEDs indicate output saturation (typically caused by loss of connection to the valve or excessively high load resistance)
• Outputs protected against inductive voltage spikes and short circuits
• Compact DIN-rail mount package
• Powered by single 24V supply
• 24V power supply isolated from inputs and outputs
