The built-in CMOS IC has high reliability and stability.

High accuracy, reciprocating error less than 1%.

Two power indicators indicate that the power is on and the time is on.

There are many types, from 24hrs, with more than 15 time ranges.

The standard exposed mounting type can be converted into a flush mounting type using a connector (Type Y-40).

AH3-3 Time Relay Wiring Method:

Time relayWhen the input action signal is added (or removed), the output circuit needs to pass through the specified accurate time to produce a jump change (or contact action) of a relay. It is an electrical component used to turn on or off a circuit with a higher voltage or a lower current to turn on or off a circuit with a higher voltage or a higher current.

When there is no power. 1-4 on.

5-8 on.

When 2-7 is connected to the power supply, 1-4 is immediately disconnected, and 1-3 is connected. When the adjustment time is reached, another relay works, that is, 5-8 is disconnected and 6-8 is turned on. This is the working step of the time relay to be directly energized.

Is no delay contact is a delay contact, wiring: 7 and 8 connected, 1 and 2 connected, the 2nd end of the button and parallel to the power supply pin, press the button foot energized and self-locking, the time relay will start timing, and the power will be cut off.

Time relay A H3 is a kind of control appliance that uses the principle of electromagnetic full or mechanical principle to achieve delay control. There are many types of it, including air damping type, electric type, electronic type and other types. At present, the most commonly used time relay is formed by large-scale integrated circuits, which uses the principle of resistance and capacitance to achieve delay action.

AH3-3 time relay is a capacitive time relay, the delay time can be adjusted, the model is AH3-3 8 pins, of which 2 and 7 are connected to the power supply A C2 20V or DC24V, the left side of the opening 1, S, 4 is a group, where 1 is the common end, 1, S is the instantaneous open contact (instantaneous moving contact), 1, 4 instantaneous often closed contact, right 5, 6, 8 is a group, 8 is the common end, 6, 8 is the delay closing contact (delay dynamic contact) 5, 8 is the delay disconnect contact ( delayed disconnection contacts).

Time relay is a kind of control appliance that uses electromagnetic principles or mechanical principles to achieve delay control. There are many types of it, including air damping type, electric type and electric judgment type. Time relays can be divided into two types: power-on delay type and power-off delay type.

There are two main ways to wire the AH3-3 time relay, as shown in the following figure:

1. Control single-wire method: the rated voltage of the time relay is 220V;

3 and 5 are connected, 6 and 8 are connected as power supply;

2. Control two-wire method: the rated voltage of the time relay is 220V;

Connect to the power supply Tong Hunger Hall.

Time relay is a very important component in the electrical control system, in many control systems, the implicit needs to use the time relay to achieve delay control.

Time relay is a kind of automatic control electrical appliance that uses the principle of electromagnetic limb air or mechanical action to delay the closing or breaking of contacts. It is characterized by a delay between the time the suction coil receives the signal and the time the contact operates. Time relays are generally used to control the starting process of motors as a function of time.

The time relay pin is connected in parallel The pin is connected to the 220V power supply, the button is normally open and the pin is connected, when the button is pressed, the time relay 1 and 3 pins are turned on, and the time relay is self-locking, and it is automatically disconnected when the set time arrives. AC contactor (can also be solenoid valve, intermediate relay, etc.) coil and time relay coil 2, 7 pins in parallel. In this way, the self-locking delay control of a single time relay can be completed.

When there is no power. 1-4 on 5-8 on When 2-7 is connected to the power supply, 1-4 is immediately disconnected, and 1-3 is turned on. When the adjustment time is reached, another relay works, that is, 5-8 is disconnected and 6-8 is turned on.

This is the working step of the time relay to be directly energized. (The status of AH3-3 remains unchanged in the case of uninterrupted power restart).

..I don't know if my diagram is the circuit you want, if it is, then there is no need to use this kind of relay, how troublesome! There is a dedicated dual-control time relay. ATDV-N is one of them.

AH3 is produced by Taiwan's An Liang Gong.

A copy of the model number ordered by the company, that is, the product BAI number.

The next 3 is the two groups of contacts, one of which is the DAO instantaneous contact and the other is the delayed contact.

From the point of view of the pin, 1 is the common pin, 4 is the normally closed point, 3 is the normally open point, this group of contacts is an instantaneous contact, that is, when the relay is energized, the 1 and 3 pins will be closed immediately.

8 is the common foot, 5 is the normally closed point and 6 is the normally open point, and this set of contacts will not be closed and connected after the time is up.

Feet 2 and 7 are power feet.
