### 4. Functionality

The ACLD‑9137F‑01 serves as a direct termination interface between a 37‑pin D‑sub connector and discrete field wiring. Each pin from the D‑sub connector is routed to a corresponding screw terminal, enabling users to connect sensors, actuators, or other external devices without soldering or crimping.

Typical Use Cases:
- Termination of analog input/output channels from ADLINK DAQ cards.
- Connection of digital I/O lines for control or monitoring applications.
- Laboratory test setups requiring quick signal reconfiguration.
- Industrial automation panels where field wiring must be easily serviceable.
- Educational and R&D environments for prototyping and signal routing.

Compatibility:
The ACLD‑9137F‑01 is compatible with ADLINK’s NuDAQ® and ACL series cards that use 37‑pin connectors, including but not limited to:
- PCI‑9111, PCI‑9112, PCI‑9114 Series
- ACL‑8112, ACL‑8216, ACL‑8312/8316
- ACL‑6126, ACL‑7120, ACL‑7130

The board can also interface with third‑party DAQ or control cards that follow the standard 37‑pin D‑sub pinout.

### 7. Performance & Capabilities

The ACLD‑9137F‑01 is a passive termination board, meaning it introduces negligible signal distortion or delay. Its performance is determined primarily by the quality of the wiring and the connected DAQ hardware.

Electrical Performance:
- Signal Integrity: Maintains low resistance and minimal crosstalk between adjacent channels.
- Frequency Response: Suitable for low‑ to medium‑frequency analog and digital signals (DC to several MHz, depending on cable length).
- Load Capacity: Supports up to 1 A per channel for control or low‑power actuation signals.
- Voltage Range: Handles up to 120 VDC or 120 VAC for signal‑level applications.

Limitations:
- No built‑in isolation, filtering, or amplification.
- Not intended for high‑power switching or high‑frequency RF signals.
