Allen Bradley 1794-OB16

Working Parameters

Voltage Level: ±24VDC is the standard nominal voltage for many control circuits in industry. Standardization to this voltage level provides compatibility with a large number of sensors, actuators and other related equipment in industrial environments. Its voltage tolerance is specially designed to allow small voltage fluctuations without interference to ensure reliable operation in industrial environments with unstable power quality.

Maximum Current Rating: It is limited to the maximum output current. Under the Allen Bradley 1794-OB16, the maximum current of each output channel will vary, but it is generally sufficient to drive standard industrial loads. When determining the load size and planning the distribution, the total current output of all 16 channels is also defined. This allows the module to turn on multiple devices at the same time without overloading and damaging components or the module itself.

Response Time: The response time is measured in milliseconds, which is important for applications that require real-time control. Fast response time is also critical in high-speed manufacturing processes or automated assembly lines, where operations need to be highly accurate, timely and efficient to prevent errors and optimize production.

Product Features

Digital Outputs Provided: The Allen Bradley 1794-OB16 is primarily designed to provide 16 digital output channels. They can be used to drive different types of industrial components such as solenoid valves, relays, indicator lights, etc. Since the outputs are digital, simple on/off control is sufficient and is a basic function in most industrial automation applications. For example, the module is used in a bottling plant where the module controls a solenoid valve that fills the liquid to the appropriate fill level.

Status Indication: The user establishes a status indication for each output channel. This allows operators and maintenance personnel to easily check the condition of the connected equipment. The LED provides a visual indication of whether the channel is open or closed. This makes the troubleshooting and maintenance process easier as you can quickly identify which channel is not operating properly and correct it. The status indication allows the overall health of the connected equipment to be quickly checked in the industrial control panel and the corresponding corrective actions to be taken.

Overview: Allen Bradley 1794-OB16 Module Quick Overview Among a range of components from Allen Bradley, the Allen Bradley 1794-OB16 is a member of the company's family of distributed I/O solutions. It works with the PLC to transfer data and control to different modules via a high-speed communication bus. It allows PLC control commands to be sent to the modules and status information to be returned, thus achieving closed-loop control. This integration is essential for complex industrial processes that require harmonious cooperation between component systems, such as in chemical manufacturing facilities, where the system must accurately control temperature, pressure, and flow.

Applications

Manufacturing bus: In manufacturing, assembly lines, machine tools, and material handling vehicles. For example, it controls the movement of robotic arms, the operation of conveyor belts, and the activation of cutting tools. In electronics manufacturing plants, it can turn soldering irons on/off, power pick-and-place robots, and illuminate inspection stations.

Process industrial automation: The Allen Bradley 1794-OB16 manages valves, pumps, and motors in the chemical, pharmaceutical, and food processing industries. It is able to control the flow rate of raw materials, the temperature of reactors, the speed of mixing equipment, and more. In pharmaceutical plants, it can help ensure the accurate metering of ingredients and the normal operation of sterilization equipment.

Building automation: In smart buildings, it is used to manage lighting, heating, ventilation, and air conditioning (HVAC) equipment, and access control. It can switch lights on and off in different areas of a building, set the temperature of air conditioning units, and control gates and doors.
