24.5 A2VCAN Voltage Outputs
The A2VCAN provides two (2) isolated outputs by converting PWM pulses to voltage outputs
dependent on the supply voltage. The outputs are isolated from both the board logic and each
other.
The relay control must be activated by the VCOMREL signal through the common of the two
relays VREL1 and VREL2. When the relays are OFF, the output voltages VO1 and VO2 are
equal to the reference voltages VR1 and VR2 at respectively. The output range is from 0% to
100% of the power supplies VPP1 and VPP2 when connected to the two outputs. Signal
resolution is 10bits (1024 values).
