1775-S5A

The Allen Bradley 1775-S5A is an I/O scanner communication adapter module tailored for use in PLC 3 systems. This device features four communication channels for robust data transmission, accompanied by status indicators for DH/DH+ communication monitoring. This allows for effective management of input and output operations, ensuring real-time tracking of system performance.

Flexibility is a notable advantage of the 1775-S5A, as it can accommodate a scanner I/O capacity of up to 2,048 I/O points, which can be any mixture according to system requirements. The backup connector feature is essential for seamless control transfer to a backup PLC-3, ensuring operational continuity in the event of primary system failure.

In terms of electrical characteristics, the maximum scanner backplane current is rated at 6.0A from +5V and 20mA from ±15V, providing ample power for various configurations. This module is designed to withstand harsh conditions, with an operating temperature range spanning from -55°C to a high of 125°C. It is equally resilient in storage, with similar temperature tolerances ensuring that it remains operational in extreme environments.

Humidity levels from 5% to 95% (non-condensing) are permissible, making this module suitable for varying climate conditions. With a maximum installation altitude of 1,000 meters, the 1775-S5A is capable of functioning effectively in a range of industrial settings. This module presents a reliable and capable solution for managing I/O scanning and communication in Allen Bradley's PLC 3 systems.
