Sensor Actuator Terminal Blocks
Terminal blocks for sensor actuators simplify wiring and improve organization in automation systems where many sensors and actuators connect to controls. In the past, you could have maybe two or three different control-output devices in a cabinet. Now, with many control-output devices, the terminal blocks help combine the signals that come from field devices into modern machine control systems. They also reduce the amount of space that is needed in the control cabinet for wiring and for making clear, structured layouts.
A sensor actuator terminal has an important benefit: the ability to manage multiple wired connections for both sensors and actuators in a singular terminal block. That means, you get reduced installation time and fewer wiring errors, all while ensuring reliable signal transmission.

In practice, terminal blocks for sensors and actuators ensure well-organized connections and direct them right into the control system. With increasing complexity in automated systems, terminal blocks ensure reliable wired connections and "safe, sound, and scalable" devices within the control cabinet network. Using them inside the control cabinet with control system wiring leads to better serviceability because each terminal block gives a clear and unambiguous separation of signals that can be tested.
Terminal Block Basics
Single Level Pass Through Terminal Blocks are used to connect two wires together with a common junction point. This is helpful when a component needs to be disconnected or isolated within a circuit. These are the most common types of terminal blocks in industrial applications.
Ground Terminal Blocks function almost exactly like most pass through terminal blocks with one exception: they are grounded. These terminal blocks have a metal connection from where the wire is terminated, all the way to the bottom of the block where it will clamp into the panel. This allows for an electrical circuit to be grounded without running a wire to the main ground connection on a breaker or surge protector.
Fused Terminal Blocks function almost exactly like most pass through terminal blocks with one exception: the presence of a fuse. This fuse provides protection for components from too much voltage or current.
Multilevel Terminal Blocks are used to connect two wires together with a common junction point, just like single pass though terminal blocks, but with the advantage of making two electrical connections in the same block. These blocks also incorporate fuses and can be grounded.
Disconnect Terminal Blocks are similar to fused blocks, however the disconnect stops the flow of electricity by lifting a lever on the terminal block. Unlike fuse blocks, they are a more permanent solution, but will not provide any protection in the event of a power surge.
