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.
Question:
What type of RTDs is the 185078E-01L FP-RTD-122 RTD Input Module designed to measure?
Answer:
The 185078E-01L FP-RTD-122 RTD Input Module is designed to measure 100 and 1,000 resistance measurements in 400 and 4000 ranges. Each channel pulses out a 0.25 mA excitation current for precise measurements.
Question:
How does the FP-RTD-122 compensate for lead resistance errors?
Answer:
The FP-RTD-122 compensates for lead resistance errors using a 3-wire configuration along with a SENSE terminal in each channel. This allows it to eliminate the errors that may arise from the resistance of the lead wires themselves.
Question:
What does the integrated microcontroller in the FP-RTD-122 do?
Answer:
The integrated microcontroller in the FP-RTD-122 scales the measurements, which helps in accurately determining the temperature or resistance.
Question:
How can the channels on the FP-RTD-122 module be configured?
Answer:
The channels on the FP-RTD-122 module can be configured for temperature units or resistance, depending on the application's requirements.
Question:
What features indicate the status of the FP-RTD-122 module?
Answer:
The FP-RTD-122 module includes POWER and READY LEDs to indicate its operational status when inserted into a FieldPoint terminal base.
