Time relay PCU-520 multifunctional, two independent times T1 and T2, contact U = 230V, I = 2x8A, 2 modules

Time relays are used for time control in industrial and home automation systems (e.g. ventilation, heating, lighting, signaling, etc.).
Action
Functions:
* DELAYED SWITCH OFF (A)
Until the relay is turned on, the contacts remain in the 1-5, 2-8 position. After the supply voltage is applied, the contacts are switched to position
1-6, 2-7 for the time t1. After the time t1 is measured, the contacts return to positions 1-5, 2-8 for the time t2. After time t2, the relay contacts return to positions 1-5, 2-8 for time t2. After the time t2, the relay contacts return to positions 1-6, 2-7. Reactivation of the relay operation mode is possible after disconnecting the supply voltage and switching it on again.
* DELAYED SWITCHING ON (B)
After the supply voltage is
