Digital Output Wiring Diagrams

The digital 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 (<26V). The outputs pull down to less than 3V when ON, which causes current to flow through the load. When the outputs are OFF, no current flows through the load.

NPN (pull down) output type characteristics are the following:

Applied voltage 26 VDC or less
Residual voltage 0.85 V or less
Maximum sink current 100 mA
Overcurrent protection multifuse - 160 mA

PNP (pull up) output type characteristics are the following:

Output voltage range 26 VDC or less
Residual voltage 0.8 V or less
Maximum source current 100 mA
Overcurrent protection multifuse - 160 mA
