High-Speed Outputs
In-Sight 5000 series vision systems feature two built-in, high-speed outputs. Both of the high-speed outputs are NPN
(current sinking) lines. The external load should be connected between the output and the positive supply voltage
(28VDC or less). The outputs pull down to 0.1VDC or less when ON (1.25VDC or less for In-Sight 5604 only), which
causes current to flow through the load. When the outputs are OFF, no current flows through the load.
Table 3-7: High-Speed Output Specifications
Specification Description
Voltage 28VDC maximum through external load.
Current
All In-Sight 5000 series
(except In-Sight 5600 series)
200mA maximum sink current.
OFF state leakage current 200µA maximum.
External load resistance 140 Ohms to 10 kOhms.
Each line rated at a maximum 200mA, protected against over-
current, short circuit and transients from switching inductive loads.
High current inductive loads require external protection diode.
In-Sight 5600 series 100mA maximum sink current.
OFF state leakage current 200µA maximum.
External load resistance 280 Ohms to 10 kOhms.
Each line rated at a maximum 100mA, protected against over-
current, short circuit and transients from switching inductive loads.
High current inductive loads require external protection diode.
Delay
12
±5µs (maximum due to opto-isolators turning ON).
High-Speed Output - NPN Configuration
The Breakout cable can be used to connect to an NPN-compatible PLC input. Connect HS OUT 0 or HS OUT 1 directly to
the PLC input. When enabled, the output pulls down the PLC input to 0VDC. For more information, refer to Breakout
Cable Specifications on page 22 .

Delay when opto-isolators turn OFF depends on the load to which the output is connected. With a 240 Ohm load, the maximum delay will be
±5µs.

If HS OUT 1 is configured as a Strobe output type within In-Sight Explorer, the maximum strobe latency is ±5µs. For more information, refer to
