H7EC
J RESET INPUT AND COUNT INPUT
The H7EC operates using its built-in Battery. If the H7EC is
connected to a device that has +V and OUT terminals that are
connected with a diode as shown in the circuit diagram, the
circuit indicated by the arrow 1 or 2 will be formed when the
device is turned OFF. As a result, the H7EC may be reset or
count by one. It is recommended that such devices not be
connected to the H7EC.
If an excessive voltage is applied to the count or reset input
terminals, the internal elements may be damaged.
Ensure that the following voltages are not exceeded:
SPNP/NPN universal voltage input model: 30 VDC
SAC/DC voltage input model:
Do not remove the outer case when voltage is being applied to
the power supply terminals or to the input terminals.
The input for the H7Ej-NFV-j is a high-impedance circuit so
influence from an induced voltage may result in malfunction.
When the input signal wiring is longer than 10 m (stray
capacitance of 120 pF/m, at room temperature), a CR filter or a
bleeder resistor should be connected.
