Product Description:

This multifunctional relay control device is designed to provide automation solutions for a broad range of applications. It can be used as a timer, counter, frequency meter, or tachometer. It allows you to activate the relay at a specific time, number of counts, frequency, or rotation speed.

This device is powered by 9 ~48 VDC. It can be used for portable devices or automobile applications.

The timer function covers almost every application that needs a timed relay action. It can be set as single delay, double delay, pulsed output, or cumulative timer. It can display the timing in either count up or count down mode. The range of timing can be as short as 0.01 second or as long as 9999 days. The timer can be activated by the power up, front key pad, or a remote switch. 

The counter and frequency meter offers advanced signal discriminator that can remove noise triggered false count. It can perform multiplication and division so that more meaningful number will be displayed. e.g, if each mold injection produces four parts but the counter only receive one pulse, user can set the counter to multiply the pulse by 4 to display the actual parts count.

For customers that use our temperature controllers, the timer can enhance the performance of their systems. One example is to cycle a circulation fan in the oven with preset time, on and off. The other example is using the alarm output of the controller to trigger the timer. When the preset temperature is reached, the alarm will start the timer. When the timer delay is reached, the timer will shut off the heater.
