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 FOUNDATION fieldbus or LOI. The
ten different modes available are explained in Table 4-1.
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.
For optimum performance, Emerson Process Management recommends
connecting the output to a Potter & Brumfield 3.2 mA DC relay (P/N
R10S-E1Y1-J1.0K).
