Connecting voltage output

This section describes how to connect voltage output to the instrument’s external control terminals. The instrument can output a DC voltage for driving sensors.

You can choose the output voltage. The maximum supplied current is 100 mA.

  • Voltage output terminal 1: 5 V, 12 V, 24 V

  • Voltage output terminal 2: 5 V, 12 V

For more information about voltage output settings, see “8.1 Configuring Voltage Output (VOUTPUT)” in the Instruction Manual.

 

You will need: a flat-head screwdriver (with a tip width of 2.6 mm) and an output cable (5 V to 24 V DC)

 

Recommended wire diameter

Single-wire

Diameter of 0.32 mm to 0.81 mm (AWG 28 to 20)

Stranded wire

0.08 mm2 to 0.32 mm2 (AWG 28 to 20)

Standard stripping length

10 mm

 CAUTION

Do not short the voltage output terminals and GND terminals.

Once the output voltage has been set for the voltage output terminal, that voltage will be output as long as the instrument is turned on. Shorting the terminals in this state could damage the instrument.

Do not apply a voltage from an external source to the voltage output terminals.

Doing so could damage the instrument.

Connect cables to voltage output terminals before turning on output.

Connecting cables to voltage output terminals while voltage is being output could damage the instrument.

1 Position the instrument so that the external control terminals on its side are facing you.

2 Press down on the button for the voltage output terminal 1 or voltage output terminal 2 with the flat-head screwdriver.

3 Insert the positive (+) cable into the terminal hole while depressing the button.

4 Remove the flat-head screwdriver from the button.

The cable will be locked in place. Pull gently on the cable and verify that it does not come out.

5 Press down on the GND terminal button with the flat-head screwdriver.

There are 10 GND terminals. The wire can be connected to any of the GND terminals.

6 Insert the negative (-) cable into the terminal hole while depressing the button.

7 Remove the flat-head screwdriver from the button.

The cable will be locked in place. Pull gently on the cable and verify that it does not come out.
