• Manufacturer: BEL [Bel Fuse Inc.]

Remote On/Off
The SLIN-02E2Ax modules feature an On/Off pin for remote On/Off operation. Two On/Off logic options are
available. In the Positive Logic On/Off option, the module turns ON during a logic High on the On/Off pin and
turns OFF during a logic Low. With the Negative Logic On/Off option, the module turns OFF during logic High
and ON during logic Low. The On/Off signal is always referenced to ground. For either On/Off logic option,
leaving the On/Off pin disconnected will turn the module ON when input voltage is present.
For positive logic modules, the circuit configuration for using the On/Off pin is shown below.
For negative logic On/Off modules, the circuit configuration is shown below.
