The IMCIS22 Control I/O Module and the IMQRS22 Quick
Response I/O Module bring four analog and three digital pro-
cess field signals into the system for processing and monitor-
ing. They output four digital and two analog signals for process
control. The IMCIS22 module and the IMQRS22 module are
interfaces between the process and the Symphony Enterprise
Management and Control System.
The IMCIS22 and IMQRS22 modules are functionally the
same; however, the IMQRS22 module provides approximately
10 times faster response for the analog inputs. By doing this,
the input signal noise rejection is lower for the IMQRS22 mod-
ule than it is for the IMCIS22 module. The process require-
ments determine the module to use for the application.
NOTE: In this instruction, any reference to I/O module means both the
IMCIS22 module and the IMQRS22 module.
Controllers perform the control functions; I/O modules pro-
vide the I/O to the controller.
Figure 1-1 shows a Harmony area controller and the Harmony
rack controllers using the rack I/O modules for I/O interface.
Personnel installing, operating, or maintaining the I/O mod-
ules should read this instruction before performing any instal-
lation, operation, or maintenance procedures. Installation
requires an engineer or technician with experience handling
electronic circuitry. Those working with the digital output
module should have experience working with and know the
precautions to take around AC/DC power. A knowledge of the
Symphony system and electronic principles is also required.
