Read full descriptionHide description
USB 2.0 digital I/O unit featuring 16 opto-coupler isolated inputs and 16 opto-coupler isolated open-collector outputs (12-24VDC). Includes USB hub function for cascading up to 4 units, interrupt support on all inputs, digital filter, and Windows/Linux driver support.
High-Density USB
Digital I/O
The DIO-1616LX-USB is a USB 2.0-compliant digital I/O unit providing 16 opto-coupler isolated inputs and 16 opto-coupler isolated open-collector outputs. With support for 12-24VDC I/O, interrupt capability on all inputs, and a built-in USB hub function, this unit is ideal for industrial control and monitoring applications.
- Fewer I/O points
- No interrupt support
- No USB hub function
- Non-isolated
- 32 total I/O points (16 in / 16 out)
- Interrupt on all inputs
- Built-in USB hub (cascade up to 4 units)
- Opto-coupler bus isolation
Built-in USB hub function — connect up to 4 DIO-1616LX-USB units to a single PC USB port, or cascade with other Contec USB devices for expanded I/O capability.
Industrial I/O
Features
The DIO-1616LX-USB is designed for reliable industrial I/O applications. Opto-coupler isolation (1000Vrms) provides excellent noise immunity. The digital filter prevents false recognition from noise or chattering. Output circuits include zener diode surge protection and overcurrent protection.
-
High-density I/O — 16 opto-isolated inputs and 16 opto-isolated outputs in a compact unit.
-
Interrupt capability — all 16 input signals can be used as interrupt request signals with edge selection.
-
Digital filter — prevents false recognition of input signals from noise or chattering (software configurable).
-
Output protection — zener diode surge voltage protection and overcurrent protection (8-channel units).
-
USB hub function — cascade multiple units from a single USB port (up to 4 units).
-
Migration friendly — connector compatible with PIO-16/16L(PCI)H and DIO-1616L-PE boards.
