With the current levels of automation, there are more and more sensorsmonitoring the production process. This increases the number of signals tobe combined and structured. Given the restricted space in the panel, this canbecome a real challenge. Our application-specific initiator/actuator terminalblocks (AIO) are specially designed for the signal wiring requirements posed byautomation now and into the future. You can benefit from tailored, really compactsolutions for the structured wiring of initiator and actuator signals with the inputand 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 clearly. More compact designs of the components and the increase in wiring density are the resulting requirements for the control cabinet components.
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 additionally be cross-connected to the adjacent terminal block via a ZQV. This achieves 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 between "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 also 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 colour. 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
