Programmable Timer Relay

Programmable timer relay is an all-in-one device with simple PLC function, available in 8, 12, 16 inputs & 8, 12, 16 outputs, high quality and factory price. The programmable timer relay provided by ATO with 12V or 24V DC supply voltage, can work as simple PLC, with intelligent and humanized control, easy to learn, understand and operate. Optional 3 output forms of transistor DC output, transistor AC output and relay output. Input compatible with PNP/NPN.

Function

• Independent control - It can replace 8, 12, 16 single-channel timer relays and each is controlled independently. The time accuracy is 0.1 second.
• Linkage control - The programmable timer relay;can be used in any combination of multi-channels without synchronization error caused by multipe single-channel timer relays. Loops can be nested arbitrarily.
• Calendar timing - Support daily (0123456 is valid) ×× Hrs;×× Min -;×× Hrs;×× Min, and;× Month;× -;× Day;× -;× Hrs timing control.
• Simple PLC - The controller supports simple logic operations, allowing 8 switch input function to be customized, and conditional timing function.
• Offline management - No need to connect the computer and mobile phone, the simple PLC can edit and set directly on the control panel with high-definition LCD display, easy to operation.

Specification

* The loads need to be powered separately from the programmable timer relay, especially when the supply voltages are different between them.

What is a timer relay?

Time relay is a very important component in electrical control system. In many control systems, time relay needs to be used to realize delay control. Time relay is an automatic control electrical appliance that uses electromagnetic principle or mechanical action principle to delay the closing or breaking of contacts. Its characteristic is that there is a delay from the time when the self-attracting coil gets the signal to the action of the contact. Time relays are generally used for motor starting process control as a function of time.

The main function of the time relay is as an executive device in simple program control. When it receives the start signal, it starts timing. After the timing is over, its working contacts open or close, thereby promoting the subsequent circuit work. Generally speaking, the delay performance of the time relay can be adjusted within the design range, so as to facilitate the adjustment of its delay time. A time relay alone may not be able to start delay closing, and then disconnect after closing for a period of time, first realize delay closing and then delay opening.
