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 HART/AMS 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, Rosemount Analytical recommends connecting
	the output to a Potter & Brumfield 3.2 mA DC relay (P/N R10S-E1Y1-J1.0K).
