When J is in low state in figure 2-8, OUT is in low state. When J is in high
state, OUT is in high state too. So OUT can output pulse signals under the
control of J.
The max output voltage and current of digital output circuit are 250V and
100mA respectively.
Another drawing of the alarming output with beeper is as figure 2-9.

Wiring of Analog Output Circuit:
There are 2 analog output circuits in AXM-IO2 modules. The terminals of
the analog output circuits are AO1+, AO1- and AO2+, AO2-. The analog
output circuit can convert anyone of 30 electrical quantities, which is
selected by user, to analog voltage or current. The analog output circuit
supplies 4 output modes, including 0 to 20mA mode, 4 to 20mA mode, 0 to
5V mode and 1 to 5V mode.
The simplified circuit is as figure 2-10.
