About 1775-S4BA

The 1775-S4BA is an I/O scanner module from the 1775 series of PLC 3 systems, which are manufactured by Allen Bradley. The 1775-S4BA is an I/O scanner message handling module that provides I/O and RS232-C channels to be used for communication purposes. The 1775-S4BA has up to 2048 high speed I/O communication inputs and outputs per scanner and also has backup system capability. It has four communication channels and also allows the user to set the I/O scan priority. It has a report generation channel to communicate with a compatible RS232 data terminal for report generation. The scanners have a thumbwheel switch below the self-test indicators which can be set to a unique number between 1 to 15 to differentiate the scanners from one another for the PLC 3 system. It is important to note that the thumbwheel switch should only be rotated when the system is turned OFF; if this instruction is not followed it could damage the system.

The communication rate for the system is 57.6 or 115.2 kBaud for the I/O channel and it is 110 baud to 19.2 kBaud for the RS232-C channel. The channel cable length is 10,000 feet at its maximum. The various scan times for the I/O are 5.5 to 6.5 milliseconds for 1 channel, 6 milliseconds for 2 channels, 6 milliseconds for 3 channels, and 6.0 to 6.5 milliseconds for 4 channels. The 1775-S4BA is recommended to be operated in a temperature range of 0 to 60 degrees Celsius and the 1775-S4BA is to be stored at a temperature range of -40 to 85 degrees Celsius. The humidity of the environment should be without condensation between 5 to 95%.
