Measured input (Thermocouple/RTD/Voltage/Current) [universal input]
• For the measured input type, terminals 10 through 12 (RB700: terminals 16 through 18) are
allocated to the measured input.
• The input types (input group) are as follows.
Input group Input type
Thermocouple
K, J, T, S, R, E, B, N (JIS C1602-1995),
PLII (NBS), W5Re/W26Re (ASTM-E988-96)
Temperature input
group
RTD
Pt100 (JIS C1604-1997), JPt100 (JIS C1604-1997, JIS C1604-1981 の Pt100)
Voltage (low) 0 to 1 V DC, 0 to 5 V DC, 1 to 5 V DC, 0 to 10 V DC
Voltage/current input
group
Current 0 to 20 mA DC, 4 to 20 mA DC
• For thermocouple input, use the appropriate compensation wire.
• For RTD input, use low resistance lead wires with no difference in resistance between the three
lead wires.
• To avoid noise induction, keep input signal wire away from instrument power line, load lines and
power lines of other electric equipment.
• For the current input specification, a shunt resistor of 250 Ω±0.02 % (Temperature characteristics:
±10 ppm/°C, Specified voltage: 0.25 W or more) must be connected between the input terminals.
