Input/Output
The operation of the output contacts varies with the operation
specifications. Before making connections, check the operation
specifications and operating conditions using the application
examples provided.
The H3CA-A and H3CA-FA do not use transformers. Simultaneous
inputting power from two or more power supplies to separate timers
or counters from a single input contact or transistor is not possible.
For the power supply of an input device, use an isolating transformer,
of which the primary and secondary windings are mutually isolated
and the secondary winding is not grounded.
A transformer is not used in the power supplies for the H3CA-A and
H3CA-FA. You can therefore receive an electrical shock by touching
the input terminals when the power supply voltage is being applied.
Take adequate precautions to protect against electrical shock.
Inputs to input signal terminals are made by shorting the individual
input terminals to the common terminal (terminal 3 for the H3CA-A or
terminal (X) for the H3CA-FA). Internal circuits may be damaged if
connections are made to any other terminals or if voltages are
applied.
If contacts are used to short the terminals, they will be switching a
low voltage (approximately 5 VDC) and current (approximately
100 µA). You must therefore use high-reliability contacts with a
contact resistance of 1 kΩ or less when shorted and residual voltage
of 1 V maximum when shorted.
The reset input will take priority if both the set and reset inputs are
turned ON simultaneously.
Others
Holding relays are used for outputs on the H3CA-A Series. Dropping
the Unit or otherwise subjecting it to shock can cause the relay to
reverse or to move to the center position.

How to Mount the Timer on Mounting
Track
When mounting a H3CA-FA Timer on a socket mounting track,
observe the following procedures:
Mounting
First hook portion A of the timer to an edge of the track and then
depress the timer in direction B.
Dismounting
Pull out portion C with a round-blade screwdriver and remove the
timer from the mounting track.
