The OPTO 22 GRV-IACIHVS-12 AC input module is a key component of the groov EPIC system, translating electrical signals from field devices (sensors and actuators) into digital language for computer monitoring and control. This 12-channel module operates on a 180-280 VAC signal and features channel-to-channel isolation, making it suitable for applications requiring independent signal processing. Its top-mounted connector with spring-clamp terminals simplifies wiring, while the swinging cover protects wiring and provides access to module information via a touch-sensitive pad. The module is hot-swappable, self-identifying, and guaranteed for life, ensuring reliable performance in industrial environments.
