17. Other Options 17.1 Shunt Resistor for Current Input

DC current input can be measured by attaching a shunt resistor (option) to the input terminals.

1 Shunt resistor (Option) and Measurement

current range

• A shunt resistor converts the DC current input into

a DC voltage. The two types shown in the right

table are available.

• The current measuring ranges are shown in the

right table, too.

2 Connection

Connect a shunt resister to each channel for the DC

current measurement.

Only one shunt resistor is to be connected to a

channel.

3 [Range/Printing range] and [Scale]

1) Range No.

The converted voltage with any shunt resistor is ±5 V

DC and the range No. is “07”.

2) Printing range

Program the printing range with the value after being

converted into a voltage.

• Minimum value:

Min. input current x shunt resistor value

• Maximum value:

Max. input current x shunt resistor value

3) Scale

Program the scale with the physical quantity against

the input current.

• Minimum value:

Physical quantity of the minimum input current

• Maximum value:

Physical quantity of the maximum input current

<Input to be printed with the trace printing: 4 to

20mA>

Use the shunt resistor of 250Ω for the

maximum measuring current of 20mA.

• Minimum value: 4 (mA) x 250 (Ω) = 1 (V)

• Maximum value: 20 (mA) x 250 (Ω) = 5 (V)

<Physical quantity of 4 to 20mA is 0 to 500
