Contec DIO-1616T-LPE Non-Isolated Digital I/O Board

The Contec DIO-1616T-LPE is a non-isolated digital I/O board for PCI Express systems, delivering 16 TTL-level inputs and 16 open-collector outputs in a low-profile form factor. Maximum input response time is 200nsec, with configurable per-bit interrupt control and integrated digital filtering to suppress noise and contact bounce across all input channels. ## Technical Specifications • I/O Channels: 16-channel unisolated TTL-level input; 16-channel unisolated open-collector output • Input Response Time: 200nsec maximum • Output Rating: 30VDC, 40mA per signal • Input Resistance: 10kΩ (1 TTL load) • Interrupt Capability: Per-bit enable/disable, edge selection, 16 input signals consolidated to single INTA output • Digital Filter: Software-configurable, applied per input channel to eliminate noise and chatter • Connector Type: Miniature ribbon 50-pin (3M 10250-52A2JL; compatible with 10150-6000EL) • Form Factor: Low-profile PCI Express card, 121.69mm (L) × 67.90mm (H) • Bus Interface: PCI Express Base Specification Rev. 1.0a x1 • Slot Compatibility: Both low-profile and standard-size slots via interchangeable bracket ## Key Features • All 16 input signals can be configured as interrupt events with individual edge selection • Digital filter mitigates false triggering from noise and mechanical chatter • Open-collector outputs rated to 30VDC and 40mA per line for direct industrial load switching • TTL input format with 10kΩ input impedance • Fast 200nsec input response for time-critical applications ## Typical Applications Industrial control systems, process automation, machinery integration, and real-time digital signal acquisition requiring low-latency I/O operations. ## Compatibility & Integration Bundled with API-PAC(W32) function library supporting Visual Basic and Visual C++. Windows and Linux drivers included. VI-DAQ library enables LabVIEW integration. Diagnostic software provided for hardware verification. Functional and connector compatibility with legacy PIO-16/16T(LPCI)H PCI cards simplifies system migrations.
