Description
The 186481A-01 is the National Instruments SCXI-1308 Current Input Terminal Block, featuring 32 channels with precision resistors for converting current to voltage. It is compatible with SCXI modules for voltage readings, and calibration services are available through Apex Waves for accuracy assurance.
The 186481A-01 is the National Instruments SCXI-1308 Current Input Terminal Block. This shielded terminal block features 32 channels with precision resistors that can convert current to voltage when measuring 0 to 20 mA and 4 to 20 mA process current sources. It is compatible with SCXI-1102/B/C and SCXI-1100 modules, allowing the data acquisition board to obtain voltage readings. The installation process involves connecting the terminal block to the SCXI module's front connector and securing it with thumbscrews. The SCXI-1308 has channel-to-channel and channel-to-earth voltage ratings of up to 30 Vrms and 42.4 Vpeak or 60 VDCs, with an operating temperature range of 0°C to 50°C. Although the SCXI-1308 is now considered obsolete, it is still available for purchase and repairs through Apex Waves. Calibration services are also offered to ensure accuracy, with options for NIST accredited calibrations or basic in-house calibration available. Contact Apex Waves for more information on calibrating the SCXI-1308.

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.
