LOGIC I/O This two-terminal logic contact can be configured either as a solid-state
relay-activated alarm or as a bi-directional calibration handshake signal to an
IMPS 4000 or SPS 4001B. The configuration of this signal depends on the
setting of the LOGIC I/O PIN MODE via fieldbus or LOI. The ten different
modes available are explained in Table 3-1.
Alarm
When configured as an alarm, this signal alerts you to an out-of-spec
condition. The output is +5 Vdc in series with a 340 ohm resistor.
