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.
