The BLUE RELAY is a 4 relay board, it can be remotely controlled via bluetooth using Android tablets or smartphones (Free APP). The BLUE RELAY does not need any driver and the pairing with the host is simple and straightforward.

The control unit has non-volatile memory that allows the maintenance of the relay settings even in the absence of power. For example if the supply voltage is removed and then restored, the relays will be positioned automatically as they were set prior to the loss of power.

The operation of the control unit is self contained and does not require a bluetooth connection always active. The bluetooth connection is only meant to set the state of the relays and may be discontinued at any time without stopping the operation of the device.

The device is equipped with 4 power relays (SPDT type)  that allow great flexibility in the control of loads. The relay status is detected and updated automatically by the software. The relays can be set in bistable (ON/OFF) or monostable (Pulse) mode. In monostable mode, the pulse duration can be set from 1 to 6550 seconds.

The control of the unit is extremely easy thanks to our Android APP, available for free for smartphones and tablets. Our Android APP can manage an unlimited numer of BLUE RELAY boards infact each BLUE RELAY has a univocal ID. The user can password protect each Board with a PIN Code (up to 9 digits).

Below are some screenshots of our software for Android. The program requires a smartphone or tablet with bluetooth connection.
The program allows to set the switching status of the 4 relays and allows to assign a descriptive label for each of them . If necessary each relay can be set in pulse mode (1...6550 seconds). The operator also has the option to set a security PIN for the Bluetooth connection. The program also takes care to show in real time the status (ON/OFF) of the relays, thus allowing the operator to know at any time the real status position for each of them without looking at the LED status reported on the board. The program supports english and italian.
We have ability to develop specific applications for the Windows environment.
