main purpose
The KG316T-R time controlled bell ringing device can automatically control the ringing or electrical appliances (with a circuit opening time of 1-99 seconds) according to the user's set time, and is widely used in schools, factories, government units, and other occasions.  

characteristic
a、 Directly control power up to 6kW
b、 Not afraid of power outages, internal automatic charging;
c、 Up to 20 times a day can be set to ring the bell;
d、 The switch time can be cycled daily or weekly;  
e、 Equipped with keyboard lock function to prevent accidental operation;
f、 All use single key operation, easy to install and debug;
g、 The daily walking time error is less than 0.5 seconds.

Main technical data

Wiring method
1. Wiring for direct control mode
The controlled electrical appliances are single-phase power supply, with power consumption not exceeding the rated value of this switch (resistive load not exceeding 30A, inductive load not exceeding 20A), and can be directly controlled using the wiring method shown in Figure 1.
2. Wiring of single-phase expansion method
If the controlled electrical appliance is supplied with single-phase power and the power consumption exceeds the rated capacity of this switch (resistive load exceeds 30A, inductive load exceeds 20A), then an AC contactor with a capacity exceeding the power consumption of the appliance is needed to expand the capacity. The wiring method is shown in Figure 2.
3. Wiring of three-phase working mode
The controlled electrical appliance is powered by three-phase power and requires an external three-phase AC contactor
a、 As shown in Figure 3, the coil voltage of the control contactor is AC220V 50/60Hz.
b、 As shown in Figure 4, the coil voltage of the control contactor is AC380V 50/60Hz.
