LYNCA VA6

VA6 is a multichannel Voltage/Current amplifier module designed to drive hydraulic valve coils (up to 4A).

VA6 has 2 versions:

VA6-S is the standard amplifier module without feedback. The board is behaving as a linear Voltage/ Current amplifier.
VA6-F is equipped with a feedback mechanism controlling the valve with an LVDT signal input.
