1120160028

The Allen Bradley 1120160028, an SST PB3 in-chassis module from the CompactLogix 5069 series, facilitates seamless communication in industrial settings. Utilizing a single channel, this module is equipped with one PROFIBUS port that enables varied baud rate capabilities ranging from 9.6 kbps to 12 Mbps. This makes it suitable for diverse data communication requirements across different applications.

The module is designed with the capacity to support bus lengths of up to 100 meters when operating at the higher baud rate of 12 Mbps, while allowing for longer distances of 1200 meters at the lower rate. Additionally, it can accommodate connections for up to 125 stations, enhancing system flexibility when deploying multiple devices.

In terms of power specifications, the 1120160028 module operates with a nominal input voltage of 24 V DC, drawing a current of 800 mA from the backplane. With a typical power dissipation rating of 4.5 watts, it maintains efficient operation without overheating concerns. The module features a 9-pin D-sub female connector, ensuring compatibility with standard connections.

For optimal performance, it mandates the use of shielded twisted pair cable to minimize noise and interference. Diagnostic LEDs are included to provide visual indications of module status, network status, and activity, enabling quick assessment of functionality and network health. The isolation voltage rating of 500 V DC protects the unit from potential electrical faults, enhancing its reliability in demanding environments.
