Basic Operation
• Before connecting the hardware device that controls the analog in-
terface, make sure that the hardware device does not output a volt-
age higher than 20% of the specified value to the pin, otherwise the
instrument will be damaged. For example, when setting the voltage
or current, the input voltage can’t exceed 12V, otherwise the instru-
ment will be damaged.
• In analog quantity remote control mode, the analog quantity input
pins should be used in combination, and cannot be partially con-
nected and partially left floating.
• Safe electrical isolation is set between this analog interface and in-
put electrode. Do not connect any ground wire of the analog inter-
face to the positive and negative terminals of the input interface.
Analog Card Interface Introduction
The analog function interface is located on the optional IT-E167. The pins de-
scription is as below.
Pins Name Type Description
4 GND Ground Ground terminal.
5 V_Monitor Analog out Voltage monitor signal. This pin gen-
erates a voltage of 0 V to 10 V to
monitor an input voltage of 0 V to the
maximum rated value.
6 I_Monitor Analog out Current monitor signal. This pin gen-
erates a voltage of 0 V to 10 V to
monitor an input current of 0 V to the
maximum rated value.
