VC2100

Voltage-to-Current Converters

The VC2100 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.

While this product was designed to interface the MMC120, RMC100, and RMC70 family of motion controllers directly to servo valves, it can be applied to any controller or application that requires a voltage-to-current conversion.

Features

Two channels of voltage-to-current conversion
Full scale output current switch-selectable from ±10mA to ±100mA in 10mA steps (each channel is set independently)
Inputs and outputs can be paralleled for output current up to ±200mA
Dual-color LEDs indicate input polarity and amplitude
Outputs protected against inductive voltage spikes and short circuits
Compact DIN-rail mount package
Use with ±12V to ±15V power supplies

VC2100-HS

The VC2100-HS voltage-to-current converter is a high-speed version of the VC2100. The 3dB frequency is 15 kHz compared to 1.4 kHz for the VC2100. This enables signal conversion for an expanded range of applications, including motion control and functional performance testing.

Besides the expanded frequency response feature, the VC2100-HS shares the same specifications as the VC2100.
