### 4. Functionality

How It Works
The PXI‑7901 relay module provides 16 independent SPDT channels for signal routing, switching, and control. Each relay has three terminals—Common (COM), Normally Closed (NC), and Normally Open (NO). In the de‑energized state, COM connects to NC; when energized, COM connects to NO. The module supports both direct software‑controlled switching and automated scan‑list operation for deterministic signal sequencing.

The TB‑6201‑01 terminal board serves as the physical interface for these relay channels. It allows users to connect external devices, sensors, or circuits to the PXI‑7901 through screw terminals, simplifying wiring and maintenance.

Use Cases and Applications
- Automated Test Equipment (ATE) signal routing.
- Industrial ON/OFF control of motors, fans, heaters, and lights.
- Laboratory automation and measurement switching.
- External high‑power relay driving.
- Limit switch monitoring and contact status sensing.
- Integration with A/D and D/A modules for data acquisition and control systems.

Compatibility
- PXI‑7901 module connects directly to PXI chassis backplane.
- TB‑6201‑01 connects via 62‑pin D‑Sub interface or ACL‑10262 cable.
- Supported operating systems: Windows 2000/XP/Vista/2003.
- Supported programming environments: VB, VC++, BCB, Delphi.
- Recommended software: ADLINK DAQBench and ADL‑SWITCH driver package.
