The module name: 4 voltage comparison module
 
Features: through the comparison of the two voltage to the control circuit on or off by
 
 
 
1.Function: the setting voltage reference input of a voltage and on the module (reference voltage can be
 
set through the adjustable resistor) comparison, when the input voltage is greater than the reference
 
voltage, the relay is closed (10-9 closed, 10-11 disconnected), when the input voltage is less than the
 
reference voltage, the relay does not operate.
 
2.Function two: two to compare respectively input voltage signals A and B, when the voltage signal is S
 
less than the voltage signal B, the relay is closed (10-9 closed, 10-11 disconnected), when the voltage
 
signal A is less than B voltage signal, the relay does not work.
 
 
Three features: the setting voltage reference input of a voltage and on the module (reference voltage can
 
be set through the adjustable resistor) comparison, when the input voltage is less than the reference
 
voltage, the relay is closed (10-9 ratio, 11-10 disconnected), when the input voltage is greater than the
 
reference voltage, the relay does not operate.
 
 
The reference voltage: This version upgrades for the enhanced version 4 voltage comparator module,
 
add the reference voltage stabilizing circuit, a reference voltage is not receiving module power supply
 
voltage change, adjustable reference voltage range can reach 0-31V.
 
Module purpose: the automobile circuit hardware, industrial equipment, laboratory testing, application

Purchasing & Delivery

Before you make your purchase, it’s helpful to know the measurements of the area you plan to place the furniture. You should also measure any doorways and hallways through which the furniture will pass to get to its final destination.
Picking up at the store
Shopify Shop requires that all products are properly inspected BEFORE you take it home to insure there are no surprises. Our team is happy to open all packages and will assist in the inspection process. We will then reseal packages for safe transport. We encourage all customers to bring furniture pads or blankets to protect the items during transport as well as rope or tie downs. Shopify Shop will not be responsible for damage that occurs after leaving the store or during transit. It is the purchaser’s responsibility to make sure the correct items are picked up and in good condition.
Delivery
Customers are able to pick the next available delivery day that best fits their schedule. However, to route stops as efficiently as possible, Shopify Shop will provide the time frame. Customers will not be able to choose a time. You will be notified in advance of your scheduled time frame. Please make sure that a responsible adult (18 years or older) will be home at that time.
In preparation for your delivery, please remove existing furniture, pictures, mirrors, accessories, etc. to prevent damages. Also insure that the area where you would like your furniture placed is clear of any old furniture and any other items that may obstruct the passageway of the delivery team. Shopify Shop will deliver, assemble, and set-up your new furniture purchase and remove all packing materials from your home. Our delivery crews are not permitted to move your existing furniture or other household items. Delivery personnel will attempt to deliver the purchased items in a safe and controlled manner but will not attempt to place furniture if they feel it will result in damage to the product or your home. Delivery personnel are unable to remove doors, hoist furniture or carry furniture up more than 3 flights of stairs. An elevator must be available for deliveries to the 4th floor and above.
