Field Configurations; Line Monitoring - Allen-Bradley AADvance T9110 Safety Manual

Field Configurations

• This approach to classifying hazardous locations is used by the United
States (National Electrical Code), Canada (Canadian Electrical Code),
Europe (CENELEC EN 60079-10) and throughout the world (IEC
60079-10).
• While hazards are associated with all of these conditions, areas are only
considered hazardous (classified) locations under definitions defined by
the NEC, CEC, IEC 60079-10, or CENELEC EN 60079-10, as
applicable.
The AADvance controller has been investigated and approved by UL for use as
Industrial Control Equipment in a general industrial environment and for use
in hazardous locations, Class I, Division 2, Groups A, B, C and D.
The following are recommended field loop circuits for line monitoring of
digital/analogue inputs.
ATTENTION: Use cable monitoring and circuit integrity cable as appropriate
for the application, as inter-channel short circuits cannot be detected by an
AADvance controller.

Line Monitoring

This section provides recommended line monitoring circuits and resistor
values. You can set-up line monitoring on the following modules:
• T9401 and T9402 Digital Input Modules
• T9431 and T9432 Analogue Input Modules
NOTE You must ensure that there is no crossover between channels.
