FOXBORO H92 Thermal resistance output module

I/O Expander Bus Communication Security Expander bus message integrity is maintained by checksum calculations on each transmitted and received message or data set. Open Input Detection The ASI module recognizes and reports any open inputs on active channels by indicating bad quality on these channels. The exception is for -10 to +10 VDC, 0 to 10 VDC, and 0 to 5 VDC inputs. Alarm and Exception Reporting No alarm or exception reports are generated by the function codes associated with the ASI module. The values input from the ASI module must be fed to a standard exception reporting block. Refer to Section 6 for more information.

Online Configuration

 All specifications in FCs 215, 216, and 217 associated with the ASI module can be changed during online configuration. When changes are made to the input channel parameters (FC 216), the channel will hold the last value for a short period, the status remains unchanged during this period. This hold time is based on the number of channels that were changed during online configuration. NOTE: Plan on a hold time of four seconds (worst case) for each FC 216 changed during online configuration. Logic Power The ASI module receives its power (+5 V) from the MMU backplane. Power connects through the top 12-pin card edge connector (P1) at the back of the ASI module.

Mounting Hardware

 Harmony rack I/O modules and termination units mount in standard ABB Automation enclosures (CAB-01, CAB-04, CAB-12). The number of modules that can be mounted in a single cabinet varies. An IEMMU11, IEMMU12, IEMMU21, or IEMMU22 module mounting unit and an NFTP01 field termination panel (FTP) are used for module and termination unit mounting respectively (Fig. 2-2). The mounting unit and termination panel both attach to the side rails in standard 483-millimeter (19-inch) enclosures. Front mount and rear mount MMU versions are available to provide flexibility in enclosure mounting. A module mounting unit is required to mount and provide power to rack-mounted modules. The unit is for mounting controllers, I/O modules, and communication interface modules. The MMU backplane connects and routes: • Controlway. • I/O expander bus.
