9.1 DRIVERS
The PPC2 AF drivers option provides eight open collector drivers for operating external valves, solenoids,
indicators, etc. When operating from the setup-driver screen (see Section 3.3.4), pressing enter will allow
the operating mode of the drivers to be set. The two modes of operation are Momentary and Toggle. A momentary
driver will change state while the corresponding driver number on the keyboard is being pressed.
In toggle mode the driver state will toggle each time the corresponding key is pressed.
Each output can sink 500 mA at 12V. However, the total output of all the activated drivers cannot exceed
one Amp. Therefore, if multiple drivers are being activated please refer to the following chart as a guide.
# OF ACTIVE
DRIVERS
MAX CURRENT
PER OUTPUT
1 500 mA
2 400 mA
3 275 mA
4 200 mA
5 160 mA
6 135 mA
7 120 mA
8 100 mA
The male connector (P/N 102478) for the DRIVERS port is supplied with the PPC2 AF accessories.
The following table and figure should be used as reference when building a cable to utilize the drivers port.
