With the current levels of automation, there are more and more sensors monitoring the production process. This increases the number of signals to be combined and structured. Given the restricted space in the panel, this can become a real challenge. Our application-specific initiator/actuator terminal blocks (AIO) are specially designed for the signal wiring requirements posed by automation now and into the future. You can benefit from tailored, highly compact solutions for the structured wiring of initiator and actuator signals with the input and output modules of a programmable logic controller (PLC).
Increasing automation increases the number of sensors and actuators within the plant. With constant space conditions within the switchgear cabinet, these sensors and actuators must be wired in a clear way. This means control cabinet components need to be more compact and wiring must be more dense.
Our A3T 1.5 three-level terminal blocks with 3.5 mm pitch meet these requirements. Depending on the variant, they each carry a different or a common potential on three levels. For example, up to 60 wires can be contacted and 30 different potentials can be routed on a width of 3.5 cm. Each potential can also be cross-connected to the adjacent terminal block via a ZQV. This ensures maximum wiring density.
The number of sensors and actuators in the field is growing. More and more potentials have to be wired, fused, or even separated in the control cabinet. One example is servomotors with the potentials plus, minus, or PE. They require clear wiring, including fused potential.
The new two-tier terminals of the A2T 4 FS and A2T 4 DT series combine up to three functions per terminal. For example, you can choose from "Disconnect, feed-through, PE" or "Fuse, feed-through, PE." Sensors and actuators can be wired conveniently and clearly on just one terminal block. The potentials can be fused or disconnected. Cross-connection channels on each level ensure safe potential distribution on the terminal strip.
Each conductor – positive, negative, signal or PE – has its own color. Incorrect wiring is prevented, while installation and maintenance are made more efficient.
Whether it's for three- or four-conductor initiators or actuators with and without a protective earth connection, we've got the perfect terminal block in our range.
Both rigid conductors and conductors with wire-end ferrules can be reliably connected directly and without the need for any tools. For maximum contact security in a minimum amount of time.
The different potentials can be tested at every contact point. Testing work in the panel is significantly speed up
