Short Description
Description:
The 1756-ESMCAP is a capacitor-based energy storage module that works with ControlLogix 5570 controllers (1756-L7x series).
It replaces typical lithium batteries by offering a maintenance-free option for preserving volatile memory during power outages or shutdowns.
This preserves vital data, such as tag values, diagnostics, and system status, without the need for battery replacement.
Unlike battery assemblies, the ESMCAP recharges quickly and provides long-term durability, making it perfect for industrial situations that require high uptime and minimum maintenance.
It fits directly into the controller housing and is essential for effective operation of L7x controllers.
