Ii + Ip - Cyclical operation in two independent intervals T1 and T2.
Operation in the function li or lp depending on the position of the control contact S.
Application of the supply voltage U when the control contact S is open start the cyclical operation in the lp function - from the interval T1 (time of switching off the output relay R), following which the output relay R is switched on for the interval T2. The cyclical operation continues until the supply voltage U is interrupted.
When the control contact S is closed, application of the supply voltage U starts operation in the li function - from switching on the output relay R for the interval T1, and after the interval T1 has lapsed, the output relay switches off for the interval T2. The cyclical operation continues until the supply voltage U is interrupted.
In the course of the relay operation, closing of the control contact S at any time will cause reset and the operation in the li function will start whereas opening of the control contact S at any time will cause reset and the operation in the lp function will start.
Relays performing the function "li + lp": RPC-1IP-...
