Description
Part Number 776572-25, the NI SCXI-1125 Voltage Input Module offers 300 Vrms of working isolation, low pass filtering, and eight analog input channels. It allows for multiplexing channels into a single channel, parallel-mode operation, and calibration for gain and offset errors, making it a versatile and reliable tool for instrumentation needs.
Part Number: 776572-25. The NI SCXI-1125 Voltage Input Module (Part Number: 776872-25) offers 300 Vrms of working isolation and low pass filtering for every analog input channel–all 8 of them. Its architecture is perfect for intensification and confinement of millivolt sources, volt sources, 0 to 20 mA, 4 to 20 mA, and thermocouples. The SCXI-1125 can multiplex its eight channels into a single channel of the DAQ gadget, while also allowing the user to add modules to expand channel count. This module additionally offers parallel-mode operation for expanded output capability. The NI SCXI-1125 contains calibration hardware to invalid out mistake sources. With programmable offset calibration, software-programmable analog switches ground the inputs of every one of the instrumentation enhancers for offset error calibration. A locally available EEPROM stores the calibration constants for each channel for each input extend in a client characterized zone. The EEPROM also stores an arrangement of factory calibration constants in permanent memory, which cannot be altered. The NI-DAQ driver software straightforwardly utilizes the calibration constants to verify for gain and offset errors. The device has an output range of ±5.0 V, and weighs 22.6 oz. It has the dimensions: 7.4 x 6.8 x 1.2 in. In this model, each channel incorporates an automatic low pass filter that the user can configure for 4 Hz or 10 kHz. With the SCXI-1125, the user can perform irregular scanning, meaning they can choose just the channels from which they need to pick information, then scan channels in any order. Each channel is independently confined with a working common-mode voltage of 300 Vrms between channels or channel to earth. Furthermore, the SCXI-1125 is CE guaranteed as double insulated, Category II of operational isolation. The NI-DAQmx 9.0 (or later versions) driver software is required to configure and program the SCXI-1125. Also, the device is compatible with any one of the following application development environments (ADEs): LabVIEW, LabWindows/CVI, Measurement Studio. The device software can be configured using the Measurement & Automation Explorer tool. SCXI-1125 End of Life Status has been announced by National Instruments, but the module will still be available for purchase and repairs by Apex Waves. The SCXI-1125 is available to be calibrated. While the recommended calibration period for individual parts varies, most parts should be calibrated either annually or every two years to ensure accuracy. If you need the SCXI-1125 calibrated, Apex Waves provides options. We offer high-quality NIST accredited calibrations through a 3rd party, with an average turnaround time of 1 to 2 weeks. When you order the SCXI-1125 with us, you can request basic (unaccredited) in-house calibration that will calibrate the part to the manufacturer specifications prior to being shipped. Call or email us today for more information about calibrating the SCXI-1125!

Distribution Cache Shipping Info and Options
Shipping Carriers: Here at Distribution Cache we ship using UPS, FedEx, DHL, or TNT. In most cases we get very competitive rates based on our volume and will be happy quote shipping cost to your location upon request. We also know that many customers would prefer to ship collect on their own account numbers and welcome this option.
Shipping Blind: We recognize that many of our customers intend to re-sell the product to their end user. We respect our customer’s relationships with their clients and offer blind shipping as an option to ensure that the package arrives in the most clandestine way possible.
Shipping Process: We take pride in the way we package your order and spare no cost in making sure that it arrives safely at your facility. In the case of new parts, we are always sure to package the factory box inside another larger box for safe transit. For reconditioned parts we often use Distribution Cache customized packaging that is specially made to protect the products from the bumps and falls present during shipment.
Shipping Options:
Next Day Air Early AM - This service is the fastest overnight delivery option available. For most locations the package will be guaranteed by 8:30AM.
Next Day Air – This service guarantees delivery by 10:30AM and is the most frequently used option for overnight shipments.
Next Day Air Saver – This cost saving overnight alternative guarantees delivery by 3PM the next day.
2nd Day Air – For domestic shipments that would take 3-5 days if shipped via Ground, sometimes having the order in 2 days is a great way to go
Ground – Ground is the most inexpensive shipping option provided. Please ask if we are doing a “free domestic ground” shipping promotion on your order. We often provide free ground shipping on larger orders.
Emergency Courier – At times we can help work with a courier service to get the part to your facility during downtimes scenarios. We prefer that the customer sets up the courier but we can be there to make sure the product is handed off to the driver. Please give us a call to see if this is an option on your order.
Please Note: Products listed as “ships today” can ship same-day if an order is placed before 4PM. For larger drives and motors we ask that notification for same-day shipments be provided by 2PM at the latest. For any products listed as “ships in 3-5 days”, please give us a call to see if this can be expedited.
