Overview
DeviceNet Communication and I/O Capacity
The 1769-ADN connects a DeviceNet network to a remote 1769 I/O rack. It allows a controller to exchange data with connected I/O modules through one DeviceNet communication channel. This setup also helps distribute I/O points across a control system.
Key configuration features include:
- Supports up to 30 connected 1769 I/O modules.
- Provides one DeviceNet communication channel.
- Supports 180 words of input data.
- Supports 180 words of output data.
Therefore, users should consider both the module count and data capacity when planning a remote I/O configuration.
Power Supply and Electrical Characteristics
The adapter uses a 24 VDC DeviceNet power supply and draws up to 90 mA. Furthermore, the power source must meet the NEC Class 2 requirement. The module also has a maximum heat dissipation of 4.7 W, which helps users assess the rack’s thermal requirements.
In addition, the 1769-ADN provides 710 VDC isolation for one minute. This rating defines its specified isolation test condition rather than its normal operating voltage.
