Overview
The ABB 1SVR440853R0000 CL-LDR.16AC2 is a compact display-equipped I/O module purpose-built for industrial relay control and signal monitoring. This module integrates 12 AC inputs with an integrated display, allowing operators and technicians to view input states directly on the unit without external monitoring equipment. It is commonly used in control panel design, machine automation, and electrical switchgear applications where real-time visibility of input signals is critical.
Key Features
- 12 AC input channels for simultaneous signal monitoring
- Integrated display for direct input state indication
- Compact DIN rail mounting for space-efficient panel layout
- AC-rated input design for standard industrial AC signaling
- Relay-based architecture suitable for general-purpose switching and control

Compatibility & Replacements
The ABB 1SVR440853R0000 is part of ABB’s CL-LDR display I/O module family. Similar modules in the same series include DC input variants (e.g., CL-LDR.16DC2), which use identical form factors and mounting but accept DC input signals instead. When replacing or upgrading control systems, verify input voltage type (AC vs. DC) and channel count against your system requirements. This module is a direct replacement for obsolete ABB display relay modules with matching pin configurations and DIN rail compatibility. Always consult ABB documentation or your system integrator to confirm compatibility with existing wiring and control logic before installation.
