1120730001

The SST Ethernet/Serial In Chassis Module, identified by part number 1120730001 from Allen Bradley, serves as a robust interface component in the ControlLogix series. It incorporates dual serial ports paired with a single Ethernet port to facilitate versatile connection options. When using the serial ports, configurations can be adjusted for data bits (5, 6, 7, or 8) and stop bits (1 or 2) to accommodate varying data requirements. This module also supports RS-232 and RS-485 electrical interfaces with an impressive 500 volts of galvanic insulation.

Data transmission via the serial ports is capable of reaching speeds ranging from 110 to 115,200 bits per second, making it suitable for both low and high-speed applications. It operates under different data transfer modes, including Direct Mode and Paging Mode, which enhance its versatility in data handling. Furthermore, this module can support up to 127 slave devices, making it an effective option for multi-device networks.

Ethernet connectivity boasts a transmission speed of 10/100 megabits per second with auto-negotiation capabilities, which further enhances its adaptability in dynamic network scenarios. The connectors consist of a 9-pin D-sub male for the serial ports and an RJ45 connector for the Ethernet port. In terms of power requirements, the device consumes 850 milliamperes at 5 volts or 1.75 milliamperes at 24 volts, allowing for integration into various electrical setups. Its operational temperature range from 0°C to 60°C provides reliable performance under standard industrial conditions.
