Note: The following precautions apply to all H3CR-A models. ■ Power Supplies ■ Input/Output For the power supply of an input device of the H3CR-A@/-A@S/-AP, use an isolating transformer with the primary and secondary Relationship between Input and Power windings mutually isolated and the secondary winding not grounded. Supply Circuits (except for H3CR-A8E) Correct The H3CR-A (except for H3CR-A8E) uses transformerless power supply. When connecting a relay or transistor as an external signal H3CR-A input device, pay attention to the following points to prevent short- G, S, R circuiting due to a sneak current to the transformerless power supply. 5, 6, 7 10 If a relay or transistor is connected to two or more Timers, the input Input terminal Power supply terminals of those Timers must be wired properly so that they will not 2 2 differ in phase, otherwise the terminals will be short-circuited to one another. Short-circuit current Incorrect H3CR-A Contact or transistor for external input signal Input Isolation transformer is required. Power supply terminal Input device Incorrect H3CR-A G, S, R 10 5, 6, 7 Input Input terminal Power terminal 2 2 supply Correct Input Power supply terminal Input device Isolation transformer The H3CR-A@/-A@S/AP’s power supply terminal 2 is a common ter- minal for input signals to the Timer. Do not disconnect the wires on terminal 2, otherwise the internal circuitry of the Timer will be dam- Input terminal aged. 10 It is impossible to provide two independent power switches as shown 5, 6, 7 below regardless of whether or not the Timers are different in phase. G, S, R Input terminal H3CR-A Input Power supply terminal 2 Make sure that the voltage is applied within the specified range, oth- erwise the internal elements of the Timer may be damaged. Input terminal 20 H3CR-A If a relay or transistor is connected to two or more Timers, the input Relationship between Input and Power 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 Supply Circuits (H3CR-A@/-A@S) another (refer to the figures below). 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 Incorrect Contact or transistor for external input signal with the common terminal (terminal 2) for the input signals. Never use terminal 10 as the common terminal for this purpose, otherwise 10 the internal circuit of the Timer will be damaged. 6 Incorrect H3CR-AP Power supply 7 10 2 H3CR-A AC or DC 5, 6, 7 power supply G, S, R 10 Input terminal 6 2 Short-circuit current H3CR-AP 7 Correct 2 10 5, 6, 7 Correct Contact or transistor for G, S, R external input signal Input terminal H3CR-A 10 AC or DC power supply 6 2 Power supply H3CR-AP 7 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 Short-circuit current high-tension voltage applied to the input terminals. 10 6 10 H3CR-AP Ry 7 H3CR-A AC or DC 5, 6, 7 2 power supply G, S, R Input terminal 2 Input Common to All H3CR-A Models contact 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 Relationship between Input and Power attention when using shielded cables. Supply Circuits (H3CR-AP) The H3CR-A@S transistor output is isolated from the internal circuitry by a photocoupler. Therefore, either NPN or PNP output is possible. H3CR-AP AC/DC power Power supply supply Input circuit 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. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
