GE Information
Digital Inputs
Digital Inputs
The iBox has eight digital inputs (DIs).
Wetting Types
All DIs require an input voltage signal large enough to turn on an optical switch. If
the DI is receiving a sufficient wetting voltage, the green LED associated with the DI
will light.
Digital Input
Thresholds
The following table shows the iBox’s ON and OFF state thresholds. Verify that
inputs do not exceed the maximum overload voltage; otherwise, the iBox may be
damaged.
