Omron NX-SL3500

Precautions for Correct Use
• Configure dual-channel inputs with safety input terminals on the same Unit. It is not always
possible to detect short circuits between safety input terminals on different Units.
•
The total length of cable connected to one test output must be as follows:
NX-SIH400 and NX-SID800: 400 m max.

Additional Information
You can detect short-circuits between two input channels with the following methods:
• Dual-channel equivalent input: "With Test Pulse"
• Dual-channel complementary input: "Without Test Pulse" and "With Test Pulse"

Devices with Semiconductor Outputs
The signal from a device with a semiconductor output, such as a light curtain, is input to a safety
input terminal (Si).
