A wiring diagram illustrating the internal connections of the relay. It shows terminals labeled A1, Y1, 15, R1, 25/21, A2, 16, 18, 26/22, 28/24, with connections indicated by lines and symbols.
Technical Description
Function A: Power on Delay Relay
Description: The timing period T begins on energization. After timing, the output(s) relay close(s).
Diagram:
A timing diagram shows the input signal U (blue bar), the control signal Y1 (black bars), and the output signals R1/R2 and R2 inst. (black bars) over time T.
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
Function Ac: On- and Off-Delay Relay with Control Signal
Description: After power-up, closing of the control contact Y1 causes the timing period T to start (timing can be interrupted by operating the Gate control contact G). At the end of this timing period, the relay closes. When control contact Y1 re-opens, the timing T starts. At the end of this timing period T, the output reverts to its initial position (timing can be interrupted by operating the Gate control contact G).
Diagram:
A timing diagram shows the input signal U (blue bar), the control signal Y1 (black bars), and the output signals R1/R2 and R2 inst. (black bars) over time T.
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
Function At: Power on Delay Relay (Summation) with Control Signal
Description: After power-up, the first opening of control contact Y1 starts the timing. Timing can be interrupted each time control contact closes. When the cumulative total of time periods elapsed reaches the pre-set value T, the output relay closes.
Diagram:
A timing diagram shows the input signal U (blue bar), the control signal Y1 (black bars), and the output signals R1/R2 and R2 inst. (black bars) over time periods t1, t2, t3, with the total time T = t1+t2+t3.
Function B: Interval Relay with Control Signal
Description: After power-up, pulsing or maintaining control contact Y1 starts the timing T. The output relay closes for the duration of the timing period T then reverts to its initial state.
Diagram:
A timing diagram shows the input signal U (blue bar), the control signal Y1 (black bars), and the output signals R1/R2 and R2 inst. (black bars) over time T.

- R2 inst.: The second output is instantaneous if the right position is selected
- T: Timing period
- U: Supply
Function Bw: Double Interval Relay with Control Signal
Description: On closing and opening of control contact Y1, the output relay closes for the duration of the timing period T.
Diagram:
A timing diagram shows the input signal U (blue bar), the control signal Y1 (black bars), and the output signals R1/R2 and R2 inst. (black bars) over time T.
Function C: Off-Delay Relay with Control Signal
Description: After power-up and closing of the control contact Y1, the output relay closes. When control contact Y1 re-opens, timing T starts. At the end of the timing period, the output(s) relay revert(s) to its/their initial state.
Diagram:
A timing diagram shows the input signal U (blue bar), the control signal Y1 (black bars), and the output signals R1/R2 and R2 inst. (black bars) over time T.
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
Function D: Symmetrical Flasher Relay (Starting Pulse Off)
Description: Repetitive cycle with two timing periods T of equal duration, with output(s) relay changing state at the end of each timing period T.
Diagram:
A timing diagram shows the input signal U (blue bar), the control signal A1Y1 (black bars), and the output signals R1/R2 and R2 inst. (black bars) over multiple time periods T.
Before power-up Y1 should be permanently connected to A1.
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
Function D: Symmetrical Flasher Relay (Starting Pulse On)
Description: Repetitive cycle with two timing periods T of equal duration, with output(s) relay changing state at the end of each timing period T.
Diagram:
A timing diagram shows the input signal U (blue bar), and the output signals R1/R2 and R2 inst. (black bars) over multiple time periods T.
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
Function H: Interval Relay
Description: On energization of the relay, timing period T starts and the output(s) relay close(s). At the end of the timing period T, the output(s) relay revert(s) to its/their initial state.
Diagram:
A timing diagram shows the input signal U (blue bar), and the output signals R1/R2 and R2 inst. (black bars) over time T.
2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)
Function Ht: Interval Relay & With Pause / Summation Control
Description: On energisation of power supply, output(s) R close(s) and timing period T starts. The timing can be interrupted / paused each time X1 energizes. When the cumulative total of time periods elapsed reaches the pre-set value T, the output(s) R revert(s) to its/their initial state. Reenergization of X1 will also cause output(s) R close(s) if the time has elapsed and restart the same operation as described at the beginning. Except for RE17*, RE22R2MMW, RENF22R2MMW, RE22R2MMU and RE22R2MJU, timing can be interrupted / paused each time Y1 energizes. The second output (R2) can be either timed (when set to "TIMED" or instantaneous (when set to "INST").
