NI |SCXI-1327| Terminal Block

【Product Overview】

The NI SCXI-1327 (Part Number: 777777-27/777687-27/185136A-01) is a specialized High-Voltage Terminal Block designed for the SCXI signal conditioning platform. Unlike standard terminal blocks, the 1327 is engineered to safely attenuate high-voltage signals before they reach the sensitive measurement modules. As National Instruments has shifted focus to newer platforms, legacy components like the SCXI-1327 OEM terminal block are becoming harder to source. We specialize in providing Genuine NI SCXI modules and accessories from our ready stock to extend the lifespan of your existing Automated Test Equipment (ATE).

【Technical Function & System Role】

The SCXI-1327 serves as the critical physical interface between your high-voltage sensors and the data acquisition system:

• Signal Attenuation: Specifically designed to extend the input range of compatible modules (typically used with SCXI-1122 or similar isolated modules) to handle voltages up to 250 Vrms.

• Cold-Junction Compensation: Features an onboard temperature sensor for accurate thermocouple measurements in high-voltage environments.

• Safety Integration: Provides a fully shielded, high-density screw terminal connector enclosure to protect operators from hazardous voltage exposure during operation.

【Inventory-Driven Selection Strategy (Complete SCXI Solution)】

The SCXI platform relies on strict compatibility between the Module and the Terminal Block. Buying the wrong block means the system won't fit or function. Based on our massive SCXI Series Inventory, here is our trade-expert guide to help you match the right part:

1. Matching the Terminal Block (The Interface):

• High Voltage Needs: Choose SCXI-1327 (This Model) or SCXI-1324 (High-voltage terminal for specific modules).

• Isothermal/Thermocouple Needs: If you are measuring temperature with standard isolation, check our stock for SCXI-1325 (Isothermal Terminal Block) or SCXI-1304 (AC/DC Coupled).

• Multi-Chassis Shielding: We also stock SCXI-1346, often used for shielded multichassis cable connections.

2. Matching the Signal Module (The Brains):

• Standard Analog Input: SCXI-1104C. A workhorse for low-voltage signals.

• Signal Filtering: SCXI-1141. If your system requires programmable elliptic filtering.

• Strain/Bridge Sensors: SCXI-1520. The universal strain gauge module.

3. The System Controller (The USB Link):

• SCXI-1600: This is the USB Data Acquisition (DAQ) module that sits in the chassis and connects the entire SCXI rack to your PC. If your communication link is down, this is usually the part to replace.

• > Trade Tip: Ensure you match the Terminal Block to the specific Module. For example, do not force a 1327 onto a module not rated for high voltage. We suggest checking your module's front label before ordering.

【Industry Application Scenarios】

• Power Grid Monitoring: Using the SCXI-1327 to attenuate line voltages for safe monitoring in substation relay testing.

• Industrial Process Control: Wiring high-voltage transducers in manufacturing plants where 110V/220V signals need to be logged by a Data acquisition system.

• Research Labs: Used in physics labs for high-potential experiments requiring isolated data collection.

【FAQ for Procurement & Traders】

Q: Can you confirm if this is the 777777-27/777687-27/185136A-017?

A: Yes. In the NI system, SCXI-1327 is the model name, and 777777-27/777687-27/185136A-01 is the orderable/assembly Part Number. We verify both the Model Name and P/N on the label before shipping.

Q: My system is showing "Open Thermocouple" errors. Is the terminal block broken?

A: It is possible the cold-junction sensor is damaged, but it could also be a wiring issue. As a hardware supplier, we cannot provide on-site troubleshooting. We suggest consulting the NI DAQmx manual or swapping the block with a spare unit to verify the fault.

Q: Do you sell the matching cables or chassis?

A: Our inventory focuses on the Modules and Terminal Blocks (like SCXI-1141 and SCXI-1327). Please send us your full "Bill of Materials" (BOM), and we will check our warehouse for any additional cabling or chassis accessories available.
