1.0 Principles of Operation 2.0 Components and Hardware The SAAFShield Communications Module in combination with the Detecting Unit is part of the system that allows users to monitor atmospheric corrosion in real time. This monitoring can be used to display and trend corrosion data over time allowing users to evaluate operational procedures, environmental factors, or other items that occur at specific times and their impact on producing a corrosive environment.

5.0 Connecting to 4-20 mA Output 6.0 Menu System The unit connects to the host control/monitoring system via a standard “3-wire” analog loop. The SAAFShield Communications Module has three push buttons to the right of the LCD display (Figure 5). Press any button to enter the menu. There are three terminals for this connection labeled as follows: • +24V Positive 24 VDC • GND 24 VDC common • 4-20mA Signal to the analog input of the host system.

8.0 Data Input and Output The SAAFShield Detecting Unit control logic interface block interprets the 4-20 mA signal originating in the SAAFShield Communications Module and produces a set of data consisting of each piece of data collected by the SAAFShield detecting unit. The block also has some failure detection capabilities. If a failure is detected the Fail bit is set and a fail code is populated.
