2.5.5 Analog Outputs

The Analog Output (AO) board provides four outputs at 0 to 20 mA (configurable for 4 to 20 mA or any span between 0 to 20 mA). When not used for an analog output, an output channel may be used to power a transmitter with 24 Vdc power. The video recorder will support up to two AO boards, for a total of eight outputs. Figure 2-4shows the terminal connections for the AO board. See Section 1 for details on all I/O board specifications.
