sequences through the rest of the channels. Voltages from the
S/H circuits drive the output circuits.

The CPU cycles through each S/H circuit in sequence to refresh
each corresponding output channel. It uses stored data to
maintain the output levels or new data to change the outputs.
Only one output channel and its corresponding S/H circuit are
selected at a time. During normal operation, this sequence
repeats continuously for each of the output channels.

Output Driver

Block

The output driver block is eight separate analog output cir-
cuits. Each of these output circuits has a voltage buffer/cur-
rent converter to produce the final analog output signal. Figure

shows the analog output circuit. These circuits adjust the

outputs as compared to the S/H output demand. Jumpers
determine whether the operational amplifier will act as a volt-
age buffer or a current converter. All outputs automatically go
to zero (0 VDC or 0 mA) at start-up or reset.

The AOM has three output signal configurations. Output mode
(current or voltage) is selectable for each output channel.
Jumpers E6 through E13 select the mode for channels 1
through 8 respectively. Jumper E3 selects the output voltage
range, 1 to 5 VDC or 0 to 10 VDC, for ALL output channels.
Refer to

for jumper settings.

NOTE: E3 selects the voltage range for ALL output channels. If the
0 to 10 VDC option is selected, ALL outputs must be configured in
voltage mode.

A current limiter in each output circuit provides short circuit
protection. For a short condition, it limits the output current to
75 mA.
