5.2 Wiring of Input Signal
 Current input 4 to 20 mA DC, voltage input 0 to 10 V DC, 1 to 5 V DC and voltage pulse input 0/12 V DC
The input signal type can be changed by moving the short bar position. Any parameter change is not required for input type
change.
 Firmly tighten each terminal screw with the tightening torque specified below. Otherwise, electric shock, fire or
the generation of heat may result.
 When using a solderless terminal lug, use ring type.

The input signal type can be changed by moving the short bar position. Any parameter change is not required for
input type change. However for a voltage input of 1 to 10 V DC, no input signal can be changed.

The number of THV-1 that can
be connected depends on the
allowable load resistance of
temperature controller being
used.
For resistance of controller,
refer to specification of the
