Source operation
Figure 12-3 shows the basic output con
fi
guration for source operation. In this case, the
external relay coil is connected between the digital output line (pins 1 to 4) and ground (pin 9).
With this con
fi
guration, the digital output line must be set HI to energize the relay, and the
maximum source current is 2mA.
Controlling digital output lines
Although the digital output lines are primarily intended for use with a device handler for
limit testing, they can also be used for other purposes such as controlling external relays or
indicator lights. You can control these lines either from the front panel or via remote as follows.
Front panel digital output control
Set digital output line logic levels from the front panel as follows:
1.
Press the MENU key.
2.
Select GENERAL, then press ENTER.
3.
Select DIGOUT, then press ENTER.
4.
Using the RANGE and cursor keys, set the digital output parameter to the desired deci-
mal value (Table 12-1). For example, to set the output lines to L, H, H, H, set the digital
output parameter value to 7.
5.
Press EXIT to return to normal display.
