Application: Voltage input 0 to 10 V DC, 1 to 5 V DC or Voltage pulse input 0/12 V DC
(Parallel connection)
THV-1 input impedance
1 to 5 V DC, 0/12 V DC: 30 kΩ
0 to 10 V DC: 68 kΩ
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
controller instruction manual.

1 +5 V output
2 0 V
3 Gradient setting input (0 to 5 V input by the gradient setter)
4 External manual mode input (0 to 5 V input by the manual setter)
5 Auto/Manual mode transfer (contact open: auto mode)
Shorting No.2 pin (0 V) with No.5 pin results in the Manual mode.
6 Open collector output (+):
Used for output of the Heater break alarm 1 or Heater break alarm 2.
7
Open collector output (−):
Used for output of the Heater break alarm 1 or Heater break alarm 2.
