Allen Bradley 1793-OW4 can be regarded as an intelligent small junction box. It is not placed in the large control cabinet but is directly installed next to the machine. It has 4 switches and can precisely control 4 devices that require 24V electricity, such as valves, indicator lights, etc. The most convenient part is that you don't need to pull a bunch of wires from the PLC cabinet. You just need a network cable to connect it to the PLC. As a supplier, we can guarantee that all products are original and brand new, with high-quality workmanship, a sturdy shell, waterproof and dustproof, and very durable in the workshop. If you need to purchase this module, please contact us at any time.
The Allen Bradley 1793-OW4 is mainly designed to address several troublesome issues. The most annoying one is wiring. Previously, each device required a separate wire to be pulled from the control cabinet. As the number of devices increased, the cabinet and the wire troughs were filled with wires, making it look like a spider web. Finding a wire or connecting a wire could take a person's entire life. With this module, a single network cable takes care of everything. The site becomes clean immediately. Moreover, if the machine breaks down, the technician no longer needs to run back and forth between the workshop and the control cabinet. By simply looking at the lights on the module, they can determine where the problem lies. There is no need to use a multimeter to measure everywhere like a lost fly.
Its maintenance focuses on "ease and efficiency". Each output port on the module has a small light. When the equipment is not working, you can simply look at the light on site to know whether it is on or off. If the PLC did not issue a command, or if the equipment itself short-circuited, there is no need for tools. What's more convenient is that it can be replaced very quickly. The wiring is plug-and-play. The old module can be unplugged, and the new module can be plugged in. The terminals do not need to be reactivated. It can be done in just a few minutes, significantly reducing the time when the machine is not working.
To put it simply, using Allen Bradley 1793-OW4 is for four words: more, faster, better, and cheaper! The most direct benefit is saving money. Cables, wire troughs, and wiring terminals are all saved. The time spent by electricians is also greatly reduced. Then there is reliability. With fewer connections, the number of fault points naturally decreases, and the system runs more stably. Finally, it is efficient. Whether it is installation or maintenance, the speed is much faster than traditional methods. If the machine is stopped, it will result in losses. It can help you minimize the downtime to the shortest.
Q1. What are the fundamental differences between it and ordinary PLC output modules?
A: The biggest difference is that it is a distributed I/O module. Ordinary modules must be installed in the PLC cabinet, while Allen Bradley 1793-OW4 can be directly installed on the machine or beside the production line, communicating with the PLC through DeviceNet or EtherNet/IP networks, achieving "extending the nerve endings of the brain to the hands and feet".
Q2. How much load can its output points drive?
A: It is a solid-state transistor output. The maximum current for each channel is 0.5A, and the voltage range is 10-30V DC. It is suitable for driving small current DC loads such as solenoid valves and indicator lights. It cannot directly drive contactors, motors, etc., which are large power or AC loads. It needs to be converted through an intermediate relay.
Q3. How should I power it?
A: It requires a 24V DC power supply to power the module itself. This power supply can be the same as the power supply of the equipment it controls, but for stability, it is usually recommended to use an independent, high-quality 24V DC switching power supply.
