Cognex DataMan 50 - Dataman 280 High-Speed Outputs

To connect the high-speed outputs to a relay, LED or similar load, connect the negative side of the load to the output and
the positive side to +24 VDC. When the output switches on, the negative side of the load is pulled down to less than 3
VDC, and 24 VDC appears across the load. Use a protection diode for a large inductive load, with the anode connected
to the output and the cathode connected to +24 VDC.

Specification Description
Voltages V

: 26 VDC through external load
V
OL
: ≤ ± 3 V @ 50 mA
Current I
MAX
: 50 mA maximum sink or source current
Each line is protected against over-current, short circuits and transients from switching inductive loads.
High current inductive loads require an external protection diode.
For NPN lines, the external load should be connected between the output and the positive supply voltage (< 26 VDC).
The output pulls down to less than 3 VDC when ON, which causes current to flow through the load. When the output is
OFF, no current flows through the load.

For PNP lines, the external load should be connected between the output and the negative supply voltage (0 VDC).
When connected to a 24 VDC power supply, the output pulls up greater than 21 VDC when ON, and current flows
through the load. (missing or bad snippet)
