Terminal Block Power Connector

The front of the IntelliBox-I/O 2100 has a terminal block screw connector for attaching to
an appropriate power source, such as those used in automation and manufacturing
industries. The terminal block connector supports a power range from 9 to 30 VDC or
9 to 24 VAC.

Notes:
 Voltage input can be 9 to 30 VDC or 9 to 24 VAC. There are polarity indicators of the
input. However, since the IntelliBox can accept VAC, polarity reversal still results in
a normal operation (IntelliBox still operates normally if the positive contact is hooked
to V-, and the negative contact is hooked to V+ of the power input).

The power input port is isolated from the inner circuitry.
 Earth ground is not required for normal operation, but is essential and required for
transient suppression, ESD protection, and EMC compliance.

Digital I/Os

The unit has two digital I/Os (UL Class III or Class 2) that you can configure as either
input or output. The digital I/Os are isolated from each other and from the inner circuitry
of the IntelliBox using opto-isolators.

When digital I/Os are configured as inputs: High-level input logic can be as low
as 3 volts with 1 mA current drawn. For higher logic level input, for example 8V or
more, a current-limiting resistor is required. The inputs are protected from polarity
reversal.
 When digital I/Os are configured as outputs: This is a solid-state relay output;
thus, it is not sensitive to polarity orientation and has low impedance.
