SPECIFICATION DESCRIPTION
Voltage 28V maximum through external load.
200mA maximum sink current.
OFF state leakage current 200 µ A maximum
External load resistance 120 to 10K Ohms
Current
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.
Both of the built-in discrete outputs (pins 4 and 5) on the In-Sight 1000 are NPN (pull-
down) lines. The external load should be connected between the output and the
positive supply voltage (<28V). The outputs pull down to 0V when ON, which causes
current to flow through the load. When the outputs are OFF, no current flows through
the load.
Figure 3-2: Discrete Output Connection Example 1
To connect to an NPN-compatible PLC input, connect Output 0 or Output 1 directly to
the PLC input. When enabled, the output pulls down the PLC input to 0V.
