Solid-state Timer
H3T
PCB-mounting Time Unit for
High-frequency Applications
Ideal for high-frequency applications with 1-ms
reset time (including during operation) either for
power resets or external resets.
High repeat accuracy --
!
2% including the initial
value.
Solid-state control output capability of up to 100 mA
permits selection from a wide variety of output
relays.
Timer operation may also be controlled through an
externally connected variable resistor.

Note:
1. Time specifications differ for H3T-A and H3T-B.
2. The desired operation/resetting system is selected by short-circuiting and opening the specified terminals.
3. A 24-pin IC socket can be used for mounting the time unit.
4. The number of terminals differs from previous single time range units.
