– **Connector Type:** 24-pin male IEEE 488 connector
– **Transfer Rate:** Up to 1.5 MB/s (IEEE 488.1 standard)
– **Compatibility:** Works with computers and controllers supporting GPIB communication

**Specifications:**

– **Physical Dimensions:** Compact form factor, dimensions typically around 10 cm x 5 cm
– **Power Requirements:** Typically powered through the GPIB bus or through an external power supply (depending on configuration)
– **Operating Temperature:** Typically -20°C to 55°C
– **Software Support:** Compatible with NI-488.2 software and other GPIB-compatible software libraries

**Product Use:**

The NI GPIB-140A module is used primarily in the following applications:

– **Laboratory Instrumentation:** Connects PCs and controllers to GPIB instruments for data acquisition, control, and analysis.
– **Industrial Automation:** Integrates GPIB-controlled instruments into automated test systems.
– **Research and Development:** Facilitates communication with GPIB instruments in research environments.

**Key Features:**

– Supports up to 14 devices on a single GPIB bus.
– High-speed data transfer capabilities.
