Allen Bradley 1746-OBP8

The Allen Bradley 1746-OBP8 that you are looking for - we, Hanhuiguan, as your professional supplier, guarantee to provide brand new products. This module is an output module of the SLC 500 series. You can regard it as 8 reliable "hands" extending from the PLC, specifically designed for precise control of various equipment in your factory. If you are planning to buy this key module to upgrade or maintain your system, now is the best time because we have the stock available and can ship immediately.

It’s main function is to receive instructions from the PLC's brain, and then connect or disconnect external circuits, thereby controlling things like indicator lights, solenoid valves, contactors (used to start and stop motors). It uses relay outputs, just like the light switches in our homes, which can control both direct current and alternating current, and is very flexible.

1. Whether Allen Bradley 1746-OBP8 is AC (alternating current) or DC (direct current), as long as the voltage and current are within the specified range, it can be controlled. It is truly a "all-purpose tool".
2. Each channel is equipped with its own "fuse". If one channel has a problem (such as a short circuit), it will only burn its own fuse, and will not affect the normal operation of the other 7 channels at all. This greatly improves the stability of the system.

1.What is "COM" on the terminal block?

A: It's the common terminal, which can be understood as the "main entrance" of the power supply. For example, if you want to control devices with the same voltage using several points, just connect the power line to COM, it's convenient.

2.The output light is on, but the equipment doesn't respond?

A: The light on indicates that the module has received the instruction. The problem lies in the external side:

Is the external device out of power?

The wiring is wrong or loose?

The equipment is broken?

The fuse has blown?

3.Can all SLC 500 racks be used?

A: Yes, they can all be used, except for the position of the CPU itself.

4.Can it directly control a large motor?

A: No! It has "weak power". Use it to control a "powerful person" (contactor), and let the "powerful person" control the large motor.

1. The PLC controls a larger "switch" (contactor) through Allen Bradley 1746-OBP8, and then the contactor controls the start and stop of the three-phase motor.
2. In pneumatic or hydraulic systems, it is used to switch the solenoid valves, thereby controlling the movement of the cylinder or hydraulic cylinder.
3. It controls the status indicator lights (red, green, yellow) or fault alarms (beeper) on the production line.
4. For example, it controls the start and stop of a small heater, fan or conveyor belt.
