Relay Expander "Jupiter-3214" for Increased Relay Output Control

TSU is designed to increase the number of relay outputs (hereinafter - RV), controlled by the device terminating object (hereinafter - OOO). The control is performed by transferring commands (switching on, switching off, operation in the mode of periodic switching of relay outputs) from the ESU to the TCU mounted on the protected object.
The TCU controls external notification and indication means by means of power relays.
