2. Key Features

- Unisolated 32-Channel TTL Inputs and 32-Channel Open-Collector Outputs:
Provides 32 input channels (negative logic, TTL level, 10 kΩ pull-up) and 32 output channels (open collector, max. 30 VDC, 40 mA per channel). Both input and output circuits operate with a response time of 200 ns or less.

- Full Interrupt Capability:
All 32 input channels can be configured as interrupt request sources. Interrupts can be enabled or disabled per bit, and the triggering edge (rising or falling) can be selected individually.

- Digital Input Filtering:
A software-configurable digital filter prevents false triggering due to noise or contact chattering. Filter time constants are adjustable via software from 0 s to 131.072 ms.

- High-Speed PCI Bus Interface:
Compliant with 32-bit, 33 MHz PCI bus specifications, supporting both 3.3 V and 5 V universal key slots. The board draws power from the +5 V PCI rail.

- Comprehensive Software Support:
Includes Windows and Linux driver libraries (API-PAC(W32)), diagnostic utilities, and sample programs. Compatible with Visual Basic, Visual C++, C#, Delphi, and gcc.

- LabVIEW Integration:
Supported by CONTEC’s VI-DAQ library, enabling seamless integration with National Instruments LabVIEW for data acquisition and control applications.

- Compact and Lightweight Design:
Board dimensions are 121.69 mm (L) × 105.68 mm (H), with a weight of approximately 100 g.

- RoHS, CE, and VCCI Certified:
