Program Retention Battery Module | Allen-Bradley 1770-XYC

Program Retention Battery Module | Allen-Bradley 1770-XYCProduct Overview The Allen Bradley 1770 XYC preserves critical volatile memory data inside classic manufacturing control systems during unexpected electrical interruptions. This hardware assembly provides standalone electrical current to hold ladder logic configurations and variable data tables inside the internal static RAM of the controller. It serves as the primary defense against catastrophic program erasure across the entire Rockwell Automation

and 1756-PB75 Primary Mounting Layout Panel Mount or Standard Rack Mount Mechanical Anchors 2 Top Mounting Tabs and 2 Bottom Mounting Tabs Operating Temperature Range 0 to 60 degrees Celsius Permissible Ambient Humidity 5 percent to 95 percent non-condensing Physical Dimensions 267 x 140 x 147 mm Regulatory Compliance UL

Feature Specification Model Number 170133-050-00 Cable Type 75 Ω Coaxial (Shielded) Length 5

Does this adapter module require manual firming or software configuration during a live hot-swap replacement

advanced diagnostics like Bode plots and polar plots—necessary for assessing machine startup and coast-down behavior—would be impossible

avoiding the reliability risks and timing jitter often found in refurbished or "rebuilt" hardware

and includes built-in Modbus RS-485 communication for digital data exchange

eliminating data collisions and ensuring that time-critical process data reaches the controller with absolute predictability

Diagnostics: Integrated self-test routines and front-panel status indicators

and small motor actuators

To ensure precise 4-20mA control

This module executes critical alarm annunciation and emergency trip functions by providing physical contact closures to external shutdown systems

you must use the BMXCPS4002 (AC) or BMXCPS3522 (DC) redundant models along with a redundant backplane
