Information About CQM1-IA121
The CQM1-IA121 is part of Omron’s CQM1 series, designed to interface AC-powered devices with programmable logic controller systems. It features 8 input points grouped under a single common, accepting 100–120 VAC signals with a typical input current of 5 mA. The unit offers an ON voltage threshold of 60 VAC minimum and an OFF voltage threshold of 20 VAC maximum, ensuring clear signal recognition. Built for robust operation, it uses DIN rail mounting, has low internal current consumption, and provides consistent performance in industrial automation environments.
Key Features:
-
8 AC input points: Monitors up to eight discrete signals with a shared common point for simplified wiring.
-
100–120 VAC operation: Handles standard industrial AC voltage ranges for compatibility with a wide range of devices.
-
Clear switching thresholds: ON at 60 VAC minimum and OFF at 20 VAC maximum for accurate signal detection.
-
Stable response times: ON delay up to 35 ms and OFF delay up to 55 ms, suitable for standard automation tasks.
-
Low input current: Draws only 5 mA per point, reducing load on connected devices.
-
DIN rail mounting: Allows quick, secure, and space-efficient installation in control panels.
-
Reliable build quality: Designed for dependable long-term operation in industrial environments.
The CQM1-IA121 delivers the reliability and precision required for accurate AC signal input handling in PLC-based control systems.
