 Special Function Terminal Blocks from ASI


With thousands of terminal blocks to select from, ASI can offer you more than a standard wire in and wire out terminal block.  In fact, we have so many unique special function terminal blocks that we are convinced we can save you time, space and money, while improving the installation, maintenance and functionality of your panel and equipment. 


Here are just a few of the special function terminal blocks that ASI offers:

Single Side Input/Output Wiring

The ASIUK5RETURN eliminates one section of wiring duct and significantly reduces the panel space required for wiring. When it comes to saving panel space this block is a real winner! More Info






Smallest DIN Rail Terminal Block

At about the same size as a quarter the ASIMT1.5 is great for tight spaces where you need a modular terminal block to connect 30 – 14 AWG.  Think “space savings” with this family of blocks.

More Info


Three and Four Level Terminal Blocks

Starting with the ASIVIOK1.5-3D/JD, this terminal block has a ground connection on the first level and then 3 feed through connections.  There are several varieties available for sensors, actuators and all types of wiring applications. More Info



Thermocouple Terminal Block

Designed to work with all types of thermocouples, the TC500 prevents cold junctions by double clamping the lead wire to the thermocouple extension lead.  Check out the unique design features here.


Shielded Twisted Pair Wiring

The ground connection on the bottom of the block simplifies the shield connection and the two wires feed through on the next two levels.  It does not get any easier or more convenient for this type of wiring application! More Info





Control Loop Disconnect Block

Two functions in this double level terminal block make it ideal for control loop applications.  The bottom level is a feed through terminal connection and the upper level is a knife disconnect making it easy to open the loop for testing. More Info



Double Level Ring Lug Connection

If you are using crimp ring lug or fork connections on the ends of your wires and you need to reduce space this product is for you.  Unlike barrier strips which are only single level, in line and take a lot of space, this block will give you two circuits in the space of one.  And you can label each level! More Info


CT Circuit Terminal Block

Sometimes referred to as a sliding link terminal block, the combination of features in this block make it ideal for CT circuits.  You can open up and short out connections, making it safe to work on the CT circuit through the use of jumpers and each block can be clearly identified.  More Info





These special function terminal blocks for industrial applications are just a few of the many options available to help you solve any wiring application.  All of these terminal blocks and many more can be found in the NEW ASI catalog. 



What about printed circuit board connections?

ASI offers thousands of terminal blocks in all types, sizes, pin spacing, current ranges, fixed and pluggable, screw clamp and spring clamp and more.  Find more information on ASI PCB terminal blocks.



We want to wish everyone a Safe and Happy Memorial Day! ASI Offices will be Closed Monday, May 27th. We will reopen on Tuesday, May 28th at 8:30 am EST
