Product Description
The Allen Bradley 1775-SR5A Scanner Communication Module, a key component in Allen Bradley PLC 3 Systems (along with Communication, Memory, and Power Supply Modules), is crucial for data backup in numerous facilities, preventing significant data loss from hardware failures or operational errors. Manufactured by Allen Bradley, part of Rockwell International, this module scans inputs and outputs, providing feedback to connected devices and supporting Data Highway Plus for efficient communication with other modules. Compatible with various Allen Bradley hardware configurations and even some non-Allen Bradley equipment, it also works with devices pre-installed with a 1775-S4A, but its memory must be cleared beforehand to avoid equipment damage and undesirable operation. Proper initial configuration, following the manufacturer's instructions, is essential for smooth operation and to prevent equipment failures or operational faults from disrupting facility operations.
Is Your Device Showing These Signs?
The Allen Bradley 1775-SR5A PLC I/O module commonly experiences issues such as backplane communication failures, often traced to corrupted firmware or damaged data tables. Resolve these by reflashing the firmware using a compatible programming terminal and verifying proper checksum values. Address I/O faults stemming from shorted field devices or wiring errors by isolating the affected circuit and inspecting for continuity issues. Power supply fluctuations induce erratic module behavior; confirm the power supply voltage is within the specified range and replace if necessary. Finally, corrosion on the edge connector causes intermittent connectivity; clean the connector with a suitable electronic cleaner and reseat the module firmly in the chassis.
Technical specifications
The Allen Bradley 1775-SR5A Scanner Communication Module is vital for data backup in Allen Bradley PLC 3 systems, preventing data loss. It scans inputs/outputs, supports Data Highway Plus communication, and is compatible with various hardware, including systems previously using a 1775-S4A (with memory cleared). Proper initial configuration is crucial to avoid equipment damage and operational disruptions.
