NXC-I/O10 Input/Output Control Card
The NXC-I/O10 Input/Output Control Card (FG2021) provides 10 Input/Output channels and LED feedback.
It acts as a logic-level input and responds to switch closures or voltage level (high/ low) changes. The Switch
(SW) and Voltage (VO) modes are set with on-board jumpers. FIG. 4 shows the I/O10 card.
The I/Os do work with AMX PC1, PC2, UPC20 and UPC20+.
Specifications
The I/Os on this card are not dry closure; they are electronic switches that float at 5V
when Off. Therefore, they should not be expected to work in situations that require
true dry contact (or dry closure).
