NOTE
!
Note: Open loop faults are not available due to HART, Modbus, and FOUNDATION Fieldbus
interfaces where a 4-20 signal cannot be used. In this case, open loop, 0mA must be
used as the diagnostic.
The Option circuit boards vary depending upon the option
selected when ordered. Only one of the three available interface
options (relays, Modbus, or FOUNDATION Fieldbus) can be
attached to the transmitter. When installed, connections to the
options are made to connectors at the bottom of the POD .

Data connection
Most controllers in the market will accept source-configured
devices. Sink-configured signals are used in older technology
controllers, which reduce the need for complete system
upgrades. In isolated-signal devices, if the controller fails or the
mA signal wires are disconnected or broken, the field device will
remain operational. Most controllers in the market will accept
isolated configured devices.
Power and 4-20mA connections are made at TB-1 and are
identical for the EC, IR, and mV Personality Boards. For user
convenience, a second set of +Ve and -Ve power terminals have
been provided to eliminate the need for a secondary junction
1 The 4-20 mA output state is refreshed at least every two seconds (once per second is typical).
