• Connect a fuse appropriate for the applied voltage and current draw, at the position shown
in the diagram.
• When the voltage input is open, the input into the unused channels is approx. 2.5 VDC for
revision
“PV: 03 RL: 07 SV: 1.2” and 0 VDC for revision “PV: 04 RL: 08 SV: 2.0”.When
the voltage input is short circuited, 0 VDC is input to them. Please shortcircuite to
prevent from the invalid values input. When the current input is open, error code
(RGEF130 input data error) occurs to the unused channels, then the invalid values are
input. The voltage input settings is recommended to the unused channels.
• The (-) poles of inputs IN0 and IN1 are connected internally.
15.7 4-ch Analog input / Temperature input module
The detail of the external power supply is: the rated supply voltage is 24 VDC, the rated input
voltage ranges from DC19.2 to 30 V including ripple. The consumption current is 60 mA
(24 VDC) when the input is not-open, output 100%. You can input voltage, current, or
temperature probes on up to 4 channels. You cannot use different types of input at the same
time.
