High Speed Output Lines
The high-speed outputs can be used as either NPN (pull-down) or PNP (pull-up) lines.
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.
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 3VDC when ON, which causes current to flow through the load. When the outputs are
OFF, no current flows through the load.
For PNP lines, the external load should be connected between the output and the negative supply voltage (0VDC).
When connected to a 24VDC power supply, the outputs pull up greater than 21VDC when ON, and current flows through
the load. When the outputs are OFF, no current flows through the load.
