Connection of Reset and Gate Inputs

For reset input, connect a contact or an open collector type transistor 
between terminals 8 and 9. The timer resets when contact is made or 
when the transistor is ON. For gate inputs, connect a contact or an 
open collector type transistor between terminals 8 and 10. The timer 
stops when contact is marked or when the transistor is ON.
Use a contact of high contact reliability, or an open collector type 
transistor with characteristics: V

μ

A max.. Use of a gate input contact with minimum contact 

bounce (chatter) is a must, since the contact bounce time will cause 
an error in timer operating time.

When connecting a solid-state circuit not of the open collector type to 
the gate or reset inputs as shown below, the voltage of the solid-
state circuit (+V) should be 13 to 30 V, and the V

CE(S)

 of the transistor 

should be less than 3 V (the current that flows from either terminal 9 
or 10 is approximately 10 mA). Moreover, it is essential that the 
circuit be ON for gate or reset input, and OFF when there is no input.

Connection of a Power Supply for 
Externally Connected Components

The H5AN has a built-in power supply for externally connected 
components such as sensors for gate or reset input, or loads 
connected to the solid-state control output (12 VDC, 80 mA).
Power can be applied to the sensors and loads simultaneously.

Simultaneous Input to a Number of 
H5AN Timers with the Same Contact or 
the Same Open Collector Transistor

A reset or gate input may be applied to two or more units of H5AN 
with only one contact or transistor as shown below. In this case, 
caution is required as a large current flows into the transistor. (The 
current that flows from H5AN is approximately 10 mA pre unit.)
