Signal OFF-delay operation (D mode) can be effectively used to keep a load operating for a certain period. For example, this function enables the cooling fan for a lamp or heater to operate for a certain period after the lamp or heater is switched OFF. 1.

Example: H3CR-A H3CR-A G, S, R 5, 6, 7 10 Input terminal 2 Timers Note: The undermentioned is common for all H3CR-A models. Power supply 2 Relationship between Input and Power Supply Circuits (except for H3CR-A8E) The H3CR-A (except for H3CR-A8E) uses transformerless power supply. When connecting a relay or transistor as an external signal input device, pay attention to the following points to prevent short-circuiting due to a sneak current to the transformerless power supply. If a relay or transistor is connected to two or more Timers, the input terminals of those Timers must be wired properly so that they will not differ in phase, otherwise the terminals will be short-circuited to one another. Incorrect Short-circuit current H3CR-A Contact or transistor for external input signal Input device Isolation transformer is required. Input terminal The H3CR-A@/-A@S/AP’s power supply terminal 2 is a common terminal for input signals to the Timer. Do not disconnect the wires on terminal 2, otherwise the internal circuitry of the Timer will be damaged. Power supply Input terminal 5, 6, 7 G, S, R 10 Input terminal H3CR-A 2 Correct Input terminal Power supply Make sure that the voltage is applied within the specified range, otherwise the internal elements of the Timer may be damaged. Input terminal It is impossible to provide two independent power switches as shown below regardless of whether or not the Timers are different in phase. Input terminal Power supply Input terminal Solid-state Multi-functional Timer H3CR-A B-129 Relationship between Input and Power Supply Circuits (H3CR-A@/-A@S) An appropriate input is applied to the input signal terminals of the H3CR-A@/-A@S when one of the input terminals is short-circuited with the common terminal (terminal 2) for the input signals. Never use terminal 10 as the common terminal for this purpose, otherwise the internal circuit of the Timer will be damaged. If a relay or transistor is connected to two or more Timers, the input terminals of those Timers must be wired properly so that they will not be different in phase or the terminals will be short-circuited to one another (refer to the figures below). Incorrect Contact or transistor for external input signal 10 6 Incorrect H3CR-AP 7 Power supply 10 2 H3CR-A AC or DC power supply 5, 6, 7 G, S, R 10 Input terminal 6 2 H3CR-AP 7 Correct Short-circuit current 2 10 5, 6, 7 G, S, R Input terminal AC or DC power supply Correct Contact or transistor for external input signal H3CR-A 10 6 2 7 H3CR-AP Power supply 2 Do not connect a relay or any other load between input terminals, otherwise the internal circuit of the Timer will be damaged due to the high-tension voltage applied to the input terminals. Short-circuit current 10 6 10 Ry AC or DC power supply 7 5, 6, 7 G, S, R H3CR-A Input terminal Input contact 2 Relationship between Input and Power Supply Circuits (H3CR-AP) H3CR-AP AC/DC power supply Input circuit Power supply circuit Since the input circuit and the power supply circuit are configured independently, the input circuit can be turned ON or OFF irrespective of the ON/OFF state of the power supply. It must be noted that a voltage equivalent to the power supply voltage is applied to the input circuit. B-130 Solid-state Multi-functional Timer H3CR-A H3CR-AP 2 Common to All H3CR-A Models With the H3CR-AP, input wires must be as short as possible. If the floating capacity of wires exceeds 1,200 pF (approx. 10 m for cables with 120 pF/m), the operation will be affected. Pay particular attention when using shielded cables. The H3CR-A@S transistor output is isolated from the internal circuitry by a photocoupler. Therefore, either NPN or PNP output is possible.
