Terminal Connections

Each 4000 series data logger has six input terminals. Two of the terminals are labeled "COM" and refer to common connections. The function of the four other terminals (CH1, CH2, CH3, and CH4) differ, depending on the model, as described in the following table:

Model Number	Terminal Label
	CH 1	CH 2	CH 3	CH 4
4000-1CW	CX	--	--	--
4000-101	--	VS	--	--
4000-411	V	VS	V	VS
4000-4CW	CX	C	CX	C
4000	CX	VS	CX	VS

Code	Description
V	0 to 10Vdc
VS	0 to 10Vdc / 1Vdc (Software switchable)
CX	4 to 20mA (with XPS switch)
C	4 to 20mA
--	Not used
