Allen-Bradley 1756-ESMCAPK ControlLogix Capacitor Energy Storage Module
The Allen-Bradley 1756-ESMCAPK is a conformally coated capacitor-based Energy Storage Module (ESM) designed for ControlLogix 5570 and GuardLogix 5570 controllers. It provides stored energy to support controller data retention during power loss. Unlike traditional battery-backed modules, it uses capacitors and does not require routine battery replacement.
