Read full descriptionHide description
16-channel isolated TTL-level digital I/O board for PCI. Features 16 inputs and 16 outputs with opto-coupler isolation, on-board isolated 5V power supply (600mA), interrupt capability on all inputs, digital filter, and Windows/Linux drivers.
Isolated TTL I/O
with Internal Power Supply
The PIO-16/16TB(PCI)H is a PCI-compliant interface board for isolated TTL-level digital signal I/O. It provides 16 input channels and 16 output channels with opto-coupler isolation for excellent noise immunity. An on-board isolated 5VDC power supply (600mA) is included, eliminating the need for an external supply in many applications.
- 16 opto-isolated TTL inputs
- Negative logic
- All inputs can be interrupt inputs
- Selectable interrupt edge (rising/falling)
- Digital filter for noise/chatter rejection
- 16 opto-isolated TTL outputs
- Negative logic
- On-board isolated 5VDC, 600mA supply
- External power supply option
- Connector-compatible with PIO-16/16TB(PCI)
Internal isolated power supply — An on-board isolated 5VDC 600mA power supply is available. You can select either this internal supply or an external power supply to drive the photo-isolation circuits, providing flexibility for different system configurations.
Advanced Features & Compatibility
The PIO-16/16TB(PCI)H includes a digital filter to prevent erroneous inputs from noise or chattering. All 16 input signals can be used as interrupt requests with selectable trigger edges. The board is connector-pin compatible with the PIO-16/16TB(PCI) for easy migration.
-
Digital filter — Prevents wrong recognition of input signals from carrying noise or chattering.
-
Interrupt capability — All 16 input signals can be used as interrupt requests. Interrupt trigger edge (rising or falling) is selectable.
-
Internal power supply — On-board isolated 5VDC, 600mA supply. External power option also available.
-
Compatibility — Connector pin assignment is compatible with PIO-16/16TB(PCI).
-
Up to 16 boards — Multiple boards can be installed in a single PC system.
