BasicTimer4X
Description
BasicTimer4X is designed to provide a simple solution for timing and triggering. It contains a DIN rail mounted hardware and a software for configuration. Is powered with 220VAC, but can be also powered over a USB port.
4 relays can be configured in two modes, independent and cyclic. Each relay can be configured separately for timing or can be disabled. On the LCD You can read the current state of any relay (On, Off or Out).

Hardware
Installation
The device have to be installed on DIN rails in electrical boxes. It have a dimension of 89mm X 107mm X 65mm, on a rail it will use 6 modules place. By installing leave always more cable, for a later manipulation. On a front side are 4 screws. Remove it and open a box. Detach the LCD cable from the PCB. Mount the bottom side on DIN rail and connect the wires to the relays. Please note that a relays have 3 pins (NO - Normally open, CO - Common and NC - Normally closed, from left to right). At this time, connect the USB mini cable to the device and configure it. Try the relay behavior, the timing and the switching function. On the PC, in the BasicTimer4X software, You can see which relays are opened. If all the functions working as needed, remove the USB mini cable and connect the LCD cable to the PCB. Connect the 220VAC power supply, and check again is everything working. Close the box with a screws.
Power supply
BasicTimer4X uses a 2A 5VDC to powering the MCU, relays and the LCD. The PSU don't need a high current, so You can use a 1.5mm2 wire for power and for switching. On the PCB is installed a switch port. It can be used to mount a reset button. By default, is shorted.
If You need a switching of the device, You can use any switch to cut of the power on the switching port. Please note that a switching port uses 220VAC.
Because the device has a low power composition, You can use it with a 5VDC power over a USB connector on the MCU (USB micro connector). This connector is used to program the device but can be also used to power it. Please note, that in a case You use the USB port for powering, You need a 2A 5VDC USB connector that is used for phone charging.
For higher stability, we discourage You to use the USB power, but if You have no 220VDC, it can be powered over USB but is less stable.
Relays
Relays are the most important part of the device. With a 4 independent relays, You can switch 4 devices, like, pumps, valves, etc. The relays can be used by load under 5A at 220VAC. Any higher load need to be done with contactor.
The relays have 3 pins (from left to right):
- NO - Normally open
- CO - Common
- NC - Normally closed
Depending of the task, You can wire it to achieve the wished behavior.
The relay status can be read from LCD and with the BasicTimer4X. On the LCD is in the upper line written the relay number (R1 R2 R3 R4) and under the relay number is presented the current status of the relay (On, Off or Out). With the BasicTimer4X software, You need first to be connected to the device, and the relay status will be presented in the lower left corner of the program.
LCD
To be able seeing the current state of any relay or from the whole device, we have installed one LCD. It have two lines, on the upper line is the relay number (R1 R2 R3 R4) and on the lower line is the relay status (On, Off or Out). The LCD is connected to the main PCB with a connector that can be detached in the time of service. The device will working no matter if the LCD is connected or not. If the LCD is disconnected, You can use the program BasicTimer4X to see which relay is on.
Contrast of the LCD can be adjusted with the trimer on the back side of the LCD.
USB connection
With a USB connection, You can power up the device, if You have no 220VAC and You can configure the parameters. Connecting will be done with a USB mini cable (the cable will be NOT delivered in a package). Connect the USB to the device and to PC. Wait 10 seconds that a device boot up and start the BasicTimer4X program to made a configuration.
