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.
