AB Rockwell PLC point I / O series has modular I / O suitable for flexible and low-cost applications, which is the key to successful control system design and operation. As the main member of Rockwell Automation integration architecture, its perfect diagnostic function and configurable characteristics enable the product to be applied to any automation system, and reduce the engineering cost through standardized design. It can be used in the remote device panel, local control panel, and can be accessed from multiple locations, including the Internet. This product fully meets the needs of users, with a density of 1 to 8 points, which can reduce the cost and size of the system.

Features include channel level diagnostics for fast troubleshooting, multiple termination options and flexibility that can save money, cabinet space and debugging / troubleshooting time, the ability to mix / Match Safe I / O on the same bus, and devicelogix that can achieve local control and rapid response.

In addition, self configuration modules are provided to reduce / simplify design and inventory.

Point I / O has four main components:

• I / O module provides field interface and system interface circuit

• communication interface module provides network interface circuit

• the terminal block unit provides wiring and signal termination for field side connections and provides system power for the backplane

• the power distribution module provides the scalability of the point I / O system and the flexibility of mixing various signal types

1734 point I / O module provides 1 to 8 points per module. The I / O module is connected to the network through a communication interface. The communication interface includes a built-in power supply, which can convert the input 24V DC power supply to 5V DC backplane power supply. Each type of communication interface (network adapter) Zui supports 13 to 17 I / O modules, and Zui provides 10A current. The I / O module receives power from the backplane. When using external power, zuido can expand the point I / O components to 63 I / O modules or 504 channels.
