Modular DIN-Rail Mount Terminal Blocks
Add as many circuits as you need with these terminal blocks and accessories. The terminal blocks clip onto DIN 3 rail and can be removed without disrupting adjacent blocks. Some also clip onto DIN 1 rail. All have screw-clamp terminals for a secure connection, reducing the chance of wire disconnecting due to vibrations, pulls, or snags. Rated UL 94 V-0, all meet flammability standards. Blocks that meet IP10 shield connections from objects larger than your hand; those that meet IP20 protect against objects larger than your fingers.
End covers fit on the open side of a block to prevent accidental contact with a live circuit.
End stops mount at the end of a group of blocks to keep them in place. Those rated IP20 provide additional protection from objects larger than your fingers.
Marker cards fit into built-in label holders on the blocks.

Thermocouple Terminal Blocks
Connect thermocouple wires without soldering or splicing. The terminals on these terminal blocks are made from same materials as thermocouples to ensure no signal is lost. Also known as barrier strips, they shield connections from each other to keep them neat and minimize the chance of short circuits. Choose a terminal block that matches your thermocouple type. You should also make sure the equipment you’re connecting it to is also compatible with the same thermocouple type.
For easy wiring, each end is labeled positive or negative. Mount these terminal blocks to a panel or machine using the mounting holes.
