Time relay with power failure memory, 1NO/NC contact, 12-264V PCU-504UNI

Time relay PCU-504UNI is a reliable device designed for time-based control in a wide range of applications – from industrial automation, through heating and ventilation systems, to lighting or signaling. Its key feature is the function of maintaining the contact state after a power failure, which ensures continuity of operation in the event of short-term power interruptions.

The device offers three operating modes: memory, delayed-on, and delayed-on with memory. The memory function maintains the contact state for the set time after a power failure, which is particularly useful in applications requiring maintaining the set configuration. Delayed-on allows delaying the circuit activation after applying voltage, and the combination of both functions – delayed-on with memory – combines
