Patented PDSIO Load
Diagnostics
PDSIO (Pulse Density Signaling
Input/Output) is a patented innovation
in the 2208e. When used in combination
with the Eurotherm TE10S Solid State
Contactor, the same wires from the 2208e
that transmit the logic output to the SSC
can be used to read back load faults, SSC
status and load RMS on-current. SSC
failure (open or short circuit) or load
failure (fuse blown, heater open circuit,
missing line voltage) alarms can be
detected, flash on the front panel and
trip alarm relays. Amperage information
can be read, displayed, and alarmed.
PDSIO information is also available on
serial communications. PDSIO is not
available on the Valve Positioner.
Alarms
Up to four process alarms may be combined
to a single alarm output. Alarms may be
full scale high or low, deviation, rate of
change or PDSIO load failure. Alarms
may be latching or non-latching and will
flash on the front panel. Blocking alarms,
which only become enabled after first
entering a safe state, are also available.
Digital Communications
EIA-485 2-wire, EIA-422 4-wire or EIA-232
serial communications is optionally available
with industry standard Modbus or
proprietary EI-Bisynch protocol.
