The USB I/O Expander provides low-cost, easy to implement
I/O expansion for the ASIC/3 programmable controller family.
Simply connect the I/O Expander to the ASIC/3 USB host port
and immediately start using the additional eight analog inputs,
eight relay outputs, and four analog outputs.

The Expander is powered solely from the host controller’s USB
port. A standard USB 2.0, A-Male to Mini-B cable carries both
communications and power. This allows easy installation—
saving wiring and installation costs. A second USB I/O Expander
can be added with the use of a standard USB powered hub.

The Expander features eight universal 0-10Vdc,12-bit
inputs, eight relay outputs with complete electrical isolation,
and four 0-10Vdc,10-bit, 20mA Max Analog Outputs.

By connecting the Expander to an ASIC/3 controller, all of the
new inputs and outputs are automatically added to the host
controller’s I/O count. This additional I/O looks identical to the
host’s native I/O and is configured the same way with Visual
