output channels and the Vcc and ground connections. Table 3-2 shows the channel and port
assignments.
These outputs are open-collector outputs with 4.7 k pullups, which can sink 12 mA while
maintaining an output voltage below 0.6 V. The rise time of the outputs is 1 sec into a 100 pF
load; you can obtain shorter rise times by adding additional pullup resistors between the output
and Vcc for that port.
Note: It is important to notice that this module has no access to the analog backplane; this
protects the backplane from faults when high voltages are available at the module
outputs.
