6B50-2

The 6B50-1 and 6B50-2 are 24-channel digital I/O boards which are compatible with the 6B Series Signal-Conditioning
Modules at the network level. Each converts commands from the host computer into logic levels suitable for interfacing with industry-standard opto-isolated digital I/O panels. All I/O channels can be configured for input or output, using bit or byte addressing. In addition, the status of the port can be read back by the host to confirm the I/O configuration Synchronized Sampling The synchronized sampling command allows data to be sampled simultaneously from all 6B11, 6B11HV, 6B12, 6B12HV modules and all 6B50 boards in a 6B Series system. Each module or board stores the data in a separate register within its microcontroller and can access the data with a separate command.

Software Configuration The 6B50-1 and 6B50-2 can be software-configured for address, baud rate, data format,checksum status and I/O configuration. All programmable parameters are stored in the nonvolatile memory of each digital I/O board.

An on-board microcontroller communicates with the host through an RS-232C port (Model 6B50-2 or with a 6B Series backplane through an RS 485 port (Model 6B50-1) to exchange command and status information.

An included EEPROM stores system parameters (address, baud rate, checksum, etc.) as well as I/O configuration information.

The microcontroller is interfaced to 8-bit latches and buffers a maximum of 24 digital i/o channels. Each channel can be
individually set as either an input or output. The 6B50-1 and 6B50-2 are 3.47-inch x 6.5-inch open boards that can be panel or rack mounted.
