Overview
The IMCIS22 Control I/O and IMQRS22 Quick Response I/O modules are part of the Symphony Enterprise Management and Control System, designed for Harmony racks. These modules handle the integration of four analog and three digital process signals from the field into the system for processing and monitoring. Additionally, they provide four digital and two analog outputs for controlling processes.Specifications
