J INPUT/OUTPUT
Relationship between Input and
Power Supply Circuits
Since the input circuit and the power supply circuit are configured
independently, the input circuit can be turned on or off
irrespective of the on/off state of the power supply.
It must be noted that a voltage equivalent to the power supply
voltage is applied to the input circuit.
When connecting a relay or a transistor as an external signal
input device, pay attention to the following points to prevent
short-circuiting due to a sneak current to the transformerless
power supply.
If a relay or transistor is connected to two or more Timers, the
input terminals of those Timers must be wired properly so that
they will not be different in phase or the terminals will be
short-circuited to one another (refer to the figures below).
Note: The H3DE Series is provided with a transformerless pow-

J INPUT WIRES
The input wires must be as short as possible. If the floating
capacity of wires exceeds 2,000 pF (approx. 17 m for cables with
120 pF/m), the operation will be affected. Pay particular attention
when using shielded cables.
J VDE CONFORMANCE
The H3DE as a built-in timer conforms to VDE 0435/P2021
provided that the following conditions are satisfied:
The output section of the H3DE is provided only with basic
isolation. To ensure reinforced isolation required by the VDE
standards, provide supplementary basic isolation on the load side
connected to the output.
The H3DE itself is designed according to the following:
•
•
The following facts are based on the above standards:
•
•
Overvoltage category III
Pollution degree 2
Operation parts on the front and bottom: Reinforced isolation
with clearance of 5.5 mm and creepage distance of 5.5 mm
at 230 VAC
Output: Basic isolation with clearance of 3 mm and creepage
distance of 3 mm at 230 VAC
