J MOUNTING CLEARANCE
If the load current is continuously being supplied to the Timer for
a long period of time, be sure to provide the mounting clearance
as shown in the figure below. If used under conditions without
this mounting clearance, an excessive rise in the internal
temperature of the components may result in a shortened
component life.

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. Note that a
voltage equivalent to the power supply voltage is applied to the
input circuit.
A Relay or Transistor as an External
Signal Input Device
When connecting a relay or a transistor as an external signal
input device, consider the following points (exemplified in the
diagrams that follow) 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).
The H3DE Series is provided with a transformerless power
supply system.
