Overview
The ABB CL-LDR.16AC2 is a professional-grade Display I/O module designed for industrial control and logic relay applications. This unit combines 12 discrete inputs with 4 relay outputs and a single analog output in a compact form factor, making it suitable for a wide range of automation and process control tasks. The 24 V AC rated supply ensures compatibility with standard industrial control power systems.
Key Features
- 12 Digital Inputs: Captures discrete signals from sensors, switches, and limit devices
- 4 Relay Outputs: Switching capability for solenoids, contactors, and control circuits
- Integrated Analog Output: Single analog channel for proportional or analog control functions
- Visual Status Indication: Built-in display for real-time monitoring of input and output states
- Compact Design: Space-efficient module suitable for panel mounting and embedded control systems
- 24 V AC Rated Supply: Operates from standard industrial control voltage
Technical Specifications
The CL-LDR.16AC2 provides robust I/O capability in a standardized package. Input circuits are isolated and designed to handle sensor-level signals, while relay outputs support both AC and DC loads. The module integrates seamlessly into ABB’s CL-range logic relay family, allowing flexible expansion and modular system design.
Typical Applications
- Manufacturing equipment control and sequencing
