1775-S4BB

The 1775-S4BB part from Allen Bradley is an advanced I/O scanner module, part of the PLC 3 series designated for extensive control applications. It is capable of managing a substantial input count, accommodating up to 2,048 discrete inputs, which is essential for complex operational setups. In terms of output handling, this module also supports up to 2,048 discrete outputs, enabling significant control over connected equipment.

The module utilizes four distinct high-speed communication channels that greatly enhance data exchange efficiency. This setup allows for the interconnection of 16 I/O chassis per communication channel, boosting the system’s expandability. The nominal scan time for this module is efficient, averaging between 5.5 milliseconds and 6.5 milliseconds, which optimizes the responsiveness of connected devices.

For connectivity, the 1775-S4BB module includes an RS-232-C serial port, facilitating communication with external systems. Temperature tolerances are notably broad; it operates effectively within a storage temperature range of -40 °C to 85 °C. Additionally, the module can function in settings with up to 80% relative humidity, both during operation and while in storage, without risk of condensation. Designed to be installed at altitudes of up to 1000 meters, this module showcases adaptability for various industrial environments.
