Allen Bradley 1734-IB8

The Allen Bradley 1734-IB8 is Rockwell's basic module, resembling a green box with 8 indicator lights. It is a "signal receiver" that can simultaneously receive 8 switch or sensor signals and report them to the PLC brain, just like a sentinel with 8 ears. Therefore, when you need to buy this stable and reliable "sentinel", it is very important to choose the right supplier. We Hanyite Automation Technology guarantee that all products are original and brand new, ensuring that your production line is at ease and worry-free.

Core interest point

1.The Allen Bradley 1734-IB8 saves both money and space because it is small in size. The electrical cabinet can be made smaller, thus saving valuable space. Moreover, it is modular, and just a few modules need to be added at specific points. There is no waste of money, and it is particularly economical.

2. Installation and maintenance are extremely convenient. The detachable terminal block can reduce the wiring workload by more than half. If a module breaks later, simply pull out the terminal block and replace it with a new one, then plug it back in. It can be done in just a few minutes, significantly reducing downtime.

3. Troubleshooting is lightning-fast. The 8 status indicator lights are its "face". If a sensor has no signal or a button is broken, just looking at the lights will tell you whether they are on or off. It is much faster than using a multimeter to search everywhere.

Key features

1.The Allen Bradley 1734-IB8 has 8 independent input points, which can simultaneously connect 8 different switches or sensors. One module can handle up to 8 of them.

2. It supports both drain mode and source mode. This is a very practical feature, meaning it is very "easy-going". Whether your sensor outputs a positive voltage or a negative voltage, it can connect to it and has strong compatibility.

3. Compact design, very small in size, about the size of a pack of cigarettes. It can be directly installed in the electrical cabinet next to the machine, without taking up space.

4. Removable terminal blocks. This is an amazing design! When wiring, you can remove the terminal block with screws, connect the wires on the table, and then "click" it back onto the module, avoiding the need to screw in the screws in the narrow electrical cabinet, which is very convenient.

5. Each input point corresponds to a green LED indicator light. If there is a signal at a certain point, the corresponding light will be on. When troubleshooting, just look at the light to know where the problem is, without having to use a multimeter to measure.

Product flowchart

On-site equipment (such as a button being pressed)

Sensor/switch powered on

Connected to a certain input point of Allen Bradley 1734-IB8

It converts this "powered-on" signal into a digital signal "1"

The "1" is transmitted through the bus to the PLC

The PLC receives the signal and starts to execute the next program (such as starting the motor)

Typical application scenarios

1. To talk about where this thing is used, it's quite common. It can be found everywhere. For instance, the safety door and the emergency stop button. It's like a "bodyguard". The large iron door in the workshop, when it opens, or the big red mushroom-shaped button on the wall, whoever presses it "pops" and immediately the signal is transmitted through it to the PLC. The PLC "whizzes" and stops all the machines at once. It's for safety!

2. Another example is the sensor signal collection. It's like an "intelligence agent". The "little eyes" (photoelectric sensors) on the production line, whether they have seen the product or not, whether the cylinder extends or not, all these "frontline" information, are all collected by it and then quickly reported to the "brain" PLC.

3. And the buttons on the operation console are all pointing to it. What are "start", "stop", "reset", "point movement", all the buttons in a row are connected to it. Workers can send commands to the machine through it as they want to operate it.

4. It can also act as a "physical examination doctor", specifically monitoring the equipment status. For example, whether the motor circuit breaker has tripped, whether the frequency converter has issued an alarm, it knows all of these and immediately informs the PLC which "comrade" is not feeling well.

5. Sometimes it is even used to count. For example, install a switch beside the conveyor belt, every time a product passes it, it "ticks" once, helping to count, or shout at a certain position: "The goods are here!"
