■ Input section
* The following types of inputs can be selected in the input section: measurement value input (1 point),
CT input (2 points), DI input (4 points) and AI input (1 point).
Selectable points depend on models. See the model selection table.
★ Measurement value input
* The input of the controlled objects is selectable with a single unit using parameter setting.
Temperature input
Thermocouple K, J, T, E, R, S, B, N, U and L
WRe 5-26, PR40-20 and PLII
Resistance temperature
detector Pt 100 and JPt 100
Analog input
Voltage
0 - 1 VDC, 0 - 5 VDC, 1 - 5 VDC
0 - 10 VDC, 0 - 10 mVDC
Current 4 - 20 mADC
*The K thermocouple is set as factory default.
★ CT input (optional)
* Heater disconnection failure is detected by CT (current detector) when the heater disconnection alarm
is effective.
* Max. 2 points are selectable (to be designated at order placement).
For models TTM-204 and 207, a single point for the CT input is provided when a single point for the
DI input is selected.
* Usable CT is “CTL-6-P-N-(S).” (For product specification, see page 7-9.)
* CT input is not selectable for analog output.
★ DI input (optional)
* The following functions can be executed with DI (digital) input.
The DI Input is an external no-voltage contact signals.
