Description
The SST-PFB-SLC is a communication module manufactured by SST for use with Allen-Bradley SLC controllers, specifically SLC 5/03 controllers or later. Here are some of the key features and applications of the module:
Compatibility: The SST-PFB-SLC module can be installed in any I/O slot in the SLC 500 rack, except slot 0, which is usually reserved for SLC processors. It is primarily used to implement distributed I/O or remote I/O architectures.
Communication capability: The module is capable of communicating with up to 96 Profibus slave devices, each of which can communicate up to 244 bytes of input data and 244 bytes of output data. For SLC interfaces, the module supports up to 32 words of direct input and output data, and up to 1000 words of M0 and M1 mapping data.
Communication ports: The SST-PFB-SLC module is equipped with two 9-pin D-shell communication ports, an RS 232 serial configuration port and a Profibus communication interface.
Transmission rate and cable: Supported Profibus transmission rate and cable distance of 9600@1200 meters; 19200@1200 m; 93.75k @ 1200 m; 187.5k @ 1000m; 500k @ 400m; 1.5M @ 200 m; At 100 meters, it is 3 meters, 6 meters, and 12 meters baud. The recommended Profibus cable is Belden 3079A, and other compatible cables are manufactured by Siemens or Bosch.
Environmental specifications: The environmental specifications of the SST-PFB-SLC include an operating temperature of 0-50 degrees Celsius, a storage temperature of 40-85 degrees Celsius, and a relative humidity of 5-95%.
Backplane current consumption: The backplane current consumption of the module at 5 volts DC is 700 MA.
Applications: SST-PFB-SLC is widely used in industrial automation and control systems, especially where distributed I/O or remote I/O architectures are required, such as factory automation, material handling, and line integration.
Configuration and diagnostics: The SST-PFB-SLC scanner module has an onboard flash memory for storing configuration files, eliminating the need for reconfiguration each time the SLC is started. This module provides standard status updates such as FDL, network and DP master diagnostic updates, as well as separate status updates for each slave device connected on the bus.
These characteristics make the SST-PFB-SLC an efficient and flexible communication module for a variety of industrial automation and process control applications.
