8.3 H-TI Module
Input
Number of inputs: H-TI-A, C: 4 channels
Isolated between each channel and between input
and CPU (For H-TI-A type, not isolated between
each channel)
H-TI-B: 2 channels
Isolated between each channel and between input
and CPU
Input type: Thermocouple input (H-TI-C, B):
K, J, R, S, B, E, T, N, PLII, W5Re/W26Re, U, L
RTD input (H-TI-A, B): JPt100, Pt100
Specify when ordering
Input range: Refer to Input range table (P. 14)
Specify when ordering
Resolution: 1
C ( F) or 0.1 C ( F)
0.01
C (Only for H-TI-B type RTD input)
Sampling cycle: H-TI-A, C: 0.5 seconds
H-TI-B: 0.1 seconds
Signal source resistance effect: Approx. 0.3
V/ (Only for thermocouple input)
Input impedance: 1 M
or more (Only for thermocouple input)
Sensor current: Approx. 0.3 mA (Only for RTD input)
Allowable influence of input lead: 10
or less (Only for RTD input)
Input filter: First order lag digital filter
Time constant: Settable from 0.1 to 100.0 seconds
(Setting 0.0: Filter off)
PV bias: -5.00 to +5.00 % of span

Performance
Measured accuracy: H-TI-A, C: 0.3 % of span 1 digit
H-TI-B:
0.1 % of span 1 digit
However, the accuracy of a thermocouple B type input of
0 to 399
C (0 to 799 F) is not guaranteed.
