–

• Each channel supplies voltage to a single connection.

• DO terminals supply the digital output voltages.

• The output switches the load directly.

Caution To prevent device malfunction, make sure the output ground and the

ground for the power supply (UO), have the same voltage.

Note For information about fuse ratings for the REM-11178, refer to the device

datasheet on ni.com/manuals.

Connection Guidelines

• Make sure that devices you connect to the REM-11178 are compatible with the module

specifications.

• Push the wire into the terminal when using a solid wire or a stranded wire with a ferrule.

• Open the terminal by pressing a screwdriver into the spring lever when using a stranded

wire without a ferrule.
