AVT1481 B

The module enables switching of the power network voltage (and not only) with signals from most electronic systems. In addition, it is possible to connect individual modules in series and power from a transformerless power supply. As an executive element, a relay controlled by the BUZ11 type MOSFET transistor is used. The signal that appears at the output of the optocoupler - the second stage of galvanic isolation - determines when the transistor is switched on. At the optocoupler input there is a Zener diode, which protects against supplying too high control voltage.

The device is particularly recommended as an executive module in automation and control systems

Selected parameters:

• full, two-step galvanic separation of the control circuit from the runtime circuit
• output element - relay
• the possibility of different connection of relay output contacts (like NC, NO etc.)
• input control signal <5,1Vdc
• plate designed as a module that can be combined into larger sets
• power supply - 3-24Vdc
• tile dimensions 82x20mm
• in the set a printed circuit board, a set of elements and documentation
