Signal Inputs
Connect the start input contact between terminals C and F, the
reset input contact between terminals C and G, the gate input
contact between terminals C and E, and the check input contact
between terminals C and D.
For each signal input contact, use a gold-plated contacts with high
reliability. Be sure that these input signals satisfy the following
requirements: a resistance of 1 kΩ (max.) and a residual voltage of 1
V (max.) when the contact is made.
Solid-state Signal Inputs
Connect the start input transistor between terminals C and F, the
reset input transistor between terminals C and G, the gate input
transistor between terminals C and E, and the check input
transistor between terminals C and D.
For signal input, use an open collector type transistor with
characteristics: V

= 20 V min., V
CE(S)
= 1 V max., IC = 50 mA min.
and I
CBO
= 0.5 μA max. In addition, be sure that the input signals
satisfy the following requirements: a resistance of 1 kΩ (max.) and a
residual voltage of 1 V (max.) when the transistor is ON, and a
resistance of 200 kΩ (min.) when the transistor is OFF.

2. Conventional time-limit contacts are symbolized as .
However, the contacts of H3CA-A are symbolized as
because timer has 8 operation modes.
