P/N	Sensor	Input Type			Wiring
		Dip Switch
203-5751	Wall-mounted	Down	1.	Use Belden #8771 shielded three-conductor cable or equivalent.
	relative		2.	Connect the RED, BLACK, and WHITE wires to the screw terminals the sensor’s con-
	humidity (RH)			nector as shown in Figure 2. Clip the SHIELD wire.
			3.	Connect the SHIELD and BLACK wires to the 0V terminal of the input board. Connect
	sensor
				the WHITE wire to the SIG terminal of the input board.
			4.	Connect the RED wire to the +12V power terminal on the input board.
			5.	Locate the input dip switch for the sensor point, and set to the OFF position (LEFT for
				MultiFlex, DOWN for 16AI). Refer to the input board’s user manual for locations of the
				input dip switches.

210-2002	Wall-mounted	Down	1.	For wiring the sensor to a Emerson Retail Solutions input board, use Belden #8761
	dewpoint sensor			shielded two-conductor cable or equivalent.
			2.	Connect the BLACK and WHITE wires to the screw terminals on the sensor’s connector
				as shown in
				Figure 3 (connect BLACK to Signal Ground and WHITE to 0-5V Output). Clip the
				SHIELD wire.
			3.	Connect the SHIELD and BLACK wires to the 0V terminal of the input board. Connect
				the WHITE wire to the SIG terminal of the input board.
			4.	Connect 24VAC (a separate 120VAC/24VAC transformer must be used P/N 640-0039)
				to the power terminal on the dewpoint sensor back plate using the BLACK and WHITE
				wires. (This 24VAC transformer must only be used to power this dewpoint sensor. Do
				not use this transformer to power additional devices.)
			5.	Locate the input dip switch for the sensor point, and set to the OFF position (LEFT for
				MultiFlex, DOWN for 16AI). Refer to the input board’s user manual for locations of the
				input dip switches.
