AC Output Module Application
Figure 3.3 illustrates a typical AC output module application. When using
high impedance loads, you may have to add an additional resistor (Rx) in
parallel with the load. Select a value for Rx that maintains a minimum
current of 50 mA RMS through the output module in the on state.

As stated earlier the decoder can transmit decoded bar code information to a
host computer or programmable controller. The three communications Communications
