Electrical Specifications of Alarm Input Terminals

(TK-C215VP12U/E only)

To prevent penetration of noise in the internal circuitry, apply a non-voltage contact signal to the ALARM input terminal. Never apply a voltage.

Apply an alarm signal for at least 200 ms. If it is shorter, it is not guaranteed that the signal will be recognized as an alarm signal.

Under the alarm status (status when the metal contact is “make”), select the contact or connecting wire such that the maximum wire resistance between the ALARM IN and ALARM GND is within 150 K.
