Block of acquaintance for UOTVZ-1 or UOIVZ-1

"Block of a familiar place for UOTVZ-1 or UOIVZ-1" is installed in the device for displaying the current time for halls of stations UOTVZ-1 (6 pcs.) or in the device for displaying time intervals for halls of stations UOIVZ-1 (3 pcs.).) of the ESICH-M Complex and is intended for displaying the sign (hours, minutes or seconds) of the current or interval time.Structurally, the sign block consists of a metal panel 2, on which the board 1 is fixed with 6 screws and nuts.
Microcontroller DD1 of the sign board, receives data via I2C bus (circuits SDA and SCL) from the controller board. The selection of the Slave address of DD1 for the I2C interface is made by setting the jumpers J1-J3 on the board, thus determining which sign (hours, minutes or seconds) will be displayed on this board. Microcontroller DD1 outputs data to LED indicators in dynamic indication mode with a frequency of 110 Hz, and power to these indicators is supplied through 13 key current stabilisers VT1-VT24..
