H3T - Omron H3CR-A Manual

Solid-state Timer
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.

Note: 1. The above timing range applies to when the internal variable resistor of H3T is used.
2. The external variable resistor may also be used by opening the terminals connected to the internal variable resistor.
