Honeywell 900R08R-0200 8 Slot Rack -Red. Power

Introduction 

The New 900 Control Station (900CR series) operator interface from Honeywell compliments the

ControlEdge HC900 Process & Safety Controller with a unique combination of predefined display

features and custom display development tools to deliver ease of use and high flexibility in an efficient and affordable package. 

The color display and finger touch user interface enhances process monitoring while simplifying online controller changes. 

The Station Designer software used to configure the interface works in conjunction with 

the ControlEdge HC900 Controller configuration software to automatically build a Control 

Station database that exactly matches the unique, user configured, controller database. 

This highly integrated operation eliminates the time-consuming task of assigning controller communication

register addresses to the operator interface parameters used to build displays.

The standard database of the Control Station allows all available controller tags to be 

imported without restriction or costly price adders, eliminating the risk of running out of tag resources in the middle of your project.

The hardware of the 900 Control Station is designed to handle tough industrial environments 

with polycarbonate case design and water tight, type 4X/IP66, front bezel assembly. and active alarm status. 

The new 900CR is the perfect solution for applications that require the operator to monitor and control more than just a single device.

 With up to four serial ports and two Ethernet ports, 

these HMI displays can connect to multiple serial and Ethernet devices simultaneously, including variable frequency drives, bar code scanners, etc. 

Series 8 I/O Overview 

This document provides technical information to configure the Series 8 I/O. 

The following Series 8 I/O items are included in this document. 

• TC/RTD 

• Analog Input – Single Ended 

• Analog Input with HART – Single Ended 

• Analog Input with HART – Differential 

• Analog Output 

• Analog Output with HART 

• Digital Input Sequence of Events (SOE) 

• Digital Input, 24 VDC 

• Digital Input Pulse Accumulation 

• Digital Output, 24 VDC 

• DO Relay Extension Board

Definitions 

• Input Output Termination Assembly (IOTA): An assembly that holds the IOM and the connections for field wiring; 

• Input Output Module (IOM): A device that contains most of the electronics required to perform a specific I/O function. 

The IOM plugs onto the IOTA. 

C300 Controller Overview 

Honeywell’s C300 Controller provides powerful and robust control for the distributed control system (DCS).  

The C300 is a node in operating Honeywell’s field-proven deterministic Control Execution Environment (CEE) 

core software. The CEE software provides a superior control execution and scheduling environment. Control 

strategies for each controller node are configured and loaded through a common Control Builder, an easy and 

intuitive engineering tool. 

In addition to a standard and robust library of pre-built function blocks and algorithms, the C300 Controller also 

supports Custom Algorithm Blocks (CABs). Custom Algorithm Blocks are similar in purpose and structure to the 

standard function blocks that are distributed with Control Builder. However, CABs have user-defined algorithms 

and data structures, allowing custom tailored strategies to be developed to specific requirements.  

The C300 controller shares its hardware design with the Series 8 I/O, offering an innovative design that reduces 

footprint and installation and maintenance costs. The C300 controller module is mounted on the C300 Input 

Output Termination Assembly (IOTA). The C300 IOTA contains only passive devices such as FTE address 

switches. Figure 1 below depicts the IOTA components.
