High-Speed Output Lines
The high-speed outputs can be used as either NPN (pull-down) or PNP (pull-up)
lines. For NPN lines, the external load should be connected between the output
and the positive supply voltage (<28V). The outputs pull down to less than 3V
when ON, which causes current to low through the load. When the outputs are
OFF, no current lows through the load.

Specification Description
Voltage 28V maximum through external load
Current 50mA maximum sink current
OFF state leakage current 100µA
External load resistance 240 Ohms to 10K Ohms
Each line rated at a maximum 50mA, protected against
over-current, short circuits and transients from switching
inductive loads. High current inductive loads require
external protection diode.
PTC
Fuse
For PNP lines, the external load should be connected between the output
and the negative supply voltage (0V). When connected to a 24VDC
power supply, the outputs pull up greater than 21V when ON, and
current lows through the load. When the outputs are OFF, no current
lows through the load.
