I/O Expansion Module for ASIC/3 Controllers


  • Eight universal 0-10Vdc inputs
  • Eight pilot duty relay outputs
  • Four analog 0-10Vdc outputs
  • Plug and play connectivity
  • Second module added via powered USB hub
  • Compact, low profile design
  • Power and communication via USB connection


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 Expert.

All ASIC/3-95XX models support a maximum of 2 USB I/O Expanders with the use of a powered USB hub. ASIC/3-95xx controllers can power one I/O Expander each, a second expander can be powered using a USB hub. We anticipate supporting up to 4 or more expanders per controller in the future
