Ordering Information

Note: 1. Specify both the model number and supply voltage when ordering for the H3CA-8H and H3CA-8.

2. The operation/resetting system depends on the selected operation mode. For details, see “Timing Chart”.

3. The 8 operation modes are as follows:

A: ON-delay operation

B: Repeat cycle operation

C: Signal ON/OFF-delay operation (1)

D: Signal OFF-delay operation (1)

E: Interval operation

F: One-shot and flicker operation

G: Signal ON/OFF-delay operation (2)

H: Signal OFF-delay operation (2)

■ Accessories (Order Separately)

Note: Track mounted socket can be used as a front connecting socket.

Specifications

■ Time Ranges

A desired time can be set within a range of 0.1 s to 9,990 hrs by combining the three thumbwheel switch modules for time setting and one module

for time unit selection.

H3CA Engineering Data Switching operations (×103) ■ Life-test Curve Reference: A maximum current of 0.15 A can be switched at 125 VDC (cosφ = 1). Maximum current of 0.1 A can be switched if L/R is 7 ms. In both cases, a life of 100,000 operations can be expected. Note: 1. The H3CA Series has been tested for the following: impulse voltages, noise (via noise simulator, for L loads, and for relay oscillation), and resistance to static electricity. 2.

H3CA How to Use Gate Signal Input How to Use Check Signal Input If a check signal is input to the timer during the lapse of a set time, the remaining set time will become 0 and the timer will enter the next control state. Also, while a check signal is being input, the elapsed time measurement of the set time is not performed. ON-delay Operation Note: 1. This timing chart indicates the gate input in operation mode A (ON-delay operation). 2. The set time is the sum of t 1 and t2.

H3CA From a solid-state circuit (proximity sensor, photoelectric sensor, or the like) with rated power supply voltage ranging from 6 to 30 VDC, input signals can also be applied by other than an open collector type transistor as shown in the following diagram. The input signal from a solid-state circuit is applied when output transistor Tr turns ON. In terms of signal voltage, the signal is input when it goes from a high to low level. Again, the residual voltage should be 1 V (max.

H3CA ■ Application Examples Standard type H3CA is used for the following application examples. In the schematic diagrams, each thick the indicates the wiring necessary for selecting the desired operation mode.

H3CA Safety Precautions How to Change Operation Mode Operate the pushbuttons of the thumbwheel switch, located at the leftmost position on the front panel to set the operation mode. Eight operation modes (A, B, C, D, E, F, G, and H) are selectable and the selected operation mode is displayed in the operation mode display window. Connecting the Operating Power Supply The H3CA-8@ contains a capacitor-drop power circuit. Use a sinusoidal power supply with a commercial frequency.
PAGE 15
H3CA 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.
