5. RECORDER OUTPUTS
Recorder outputs DC [V] can be taken out from the recorder output terminal (pin 1, pin 20) of the
I/O connector on the rear panel of the controller.
The following three outputs are available by setting the DIP switch.
Refer to 3.2 "How to Set the DIP Switch".

The output is 0 to 10 V and is delivered linearly to the pressure indication.
The relationship between the pressure indication and recorder output voltage is as shown below.

Convert pressure using the following equation.
(Pa): P = (1×10
+3
) × V
／
10
⇔ V = 10
× P
／
(1×10
+3
)
P: Pressure (Pa) V: Output voltage (V)
(Torr): P = (1×10
+1
) × V
／
10
⇔ V = 10 × P ／
(1×10
+1
)
P: Pressure (Torr) V: Output voltage (V)
Voltage values on order of several mV are low in accuracy because the recorder output is 12-bit
DAC.
If a linear output of 10
-1
to 10
+0
Pa (10

to 10
0-2
Torr) range is required, use the 1.0

Linear signals of pressure of 1.0
