Installation
■ Terminal Arrangement
■ Input Connections
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.
H3CA-A
Note: 1. *C: Check: 3-4
2. Conventional time-limit contacts are symbolized as
*G: Gate: 3-5
*S: Start: 3-6
*R: Reset: 3-7
However, the contacts of H3CA-A are symbolized as
because timer has 8 operation modes.

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
and I
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
CBO
*G: Gate: X-D1
*S: Start: X-C1
*R: Reset: X-B1
However, the contacts of H3CA-FA are symbolized
as
