Description
arrow2_down
This Harmony RE17R timing relay can be set between 0.1 seconds and 100 hours, has an output rating of 8A, is 17.5mm wide and can be supplied with 24V DC, 24V to 240V AC. It also has 1 changeover contact SPDT (single pole double throw). It has one of market slimmest form-factors, allowing for a flexible and easy installation on DIN rail, using the same space as any modular 1-pole DIN device. It also offers a sealable cover, simple and precise settings with rotary trimmers. Multi function timer for a simple integration in hard-wired logic schematics, ideal for refurbishment of old installations without using a PLC.

Wiring Diagram


1) Contact Y1:

  • Control for functions B, C, Ac, Bw, Ad, Ah, N, O, W, T, Tt.

  • Partial stop for functions At, Ht and Pt.

  • Function D if Di selected.

  • Not used for functions A, H and P.


Technical Description
arrow2_down
Function A : Power on Delay Relay
Description

The timing period T begins on energisation. After timing, the output(s) R close(s). The second output can be either timed or instantaneous.

Function: 1 Output


Function: 2 Outputs


2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)


Function Ac: On-Delay & Off-Delay with Control Signal
Description

After energisation of power supply and energization of Y1 causes the timing period T to start.

At the end of this timing period, the output(s) R close(s).

When deenergization of Y1, the timing T starts.

At the end of this timing period T,the output(s) R revert(s) to its/their initial position.

The second output (R2) can be either timed (when set to "TIMED") or instantaneous (when set to "INST").

Function: 1 Output


Function: 2 Outputs



Function At : Power on Delay Relay (Summation) with Control Signal
Description

After power-up, the first opening of control contact C 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.

Function: 1 Output


T = t1 + t2 +...


Function B : Interval Relay with Control Signal
Description

After power-up, pulsing or maintaining control contact C starts the timing T. The output R closes for the duration of the timing period T then reverts to its initial state.

Function: 1 Output



Function Bw : Double Interval Relay with Control Signal
Description

On closing and opening of control contact C, the output R closes for the duration of the timing period T.

Function: 1 Output



Function C : Off-Delay Relay with Control Signal
Description

After power-up and closing of the control contact C, the output R closes. When control contact C re-opens, timing T starts. At the end of the timing period, the output(s) R revert(s) to its/their initial state. The second output can be either timed or instantaneous.

Function: 1 Output


Function: 2 Outputs


2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)


Function D: Symmetrical Flashing Relay (Starting Pulse Off)
Description

On energisation of power supply, output(s) R starts at its/their initial state for timing duration T then change(s) to output(s) R close(s) for the same timing duration T.This cycle is repeated indefintely until power supply removal.Specially for RE17*, RE22R2AMU, RE22R2MMW, RE22R2MMU, RE22R2MJU,this D function can only be initiated by energizing Y1 permanently.The second output (R2) can be either timed (when set to "TIMED") or instantaneous (when set to "INST").

Function: 1 Output


Function: 2 Outputs


Function: 1 Output with Retrigger / Restart Control


Function: 2 Output with Retrigger / Restart Control



Function Di : Symmetrical Flasher Relay (Starting Pulse On)
Description

Repetitive cycle with two timing periods T of equal duration, with output(s) R changing state at the end of each timing period T.

The second output can be either timed or instantaneous.

Function: 1 Output


Function: 2 Outputs


2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.)


Function H : Interval Relay
Description

On energisation of the relay, timing period T starts and the output(s) R close(s). At the end of the timing period T, the output(s) R revert(s) to its/their initial state. The second output can be either timed or instantaneous.

Function: 1 Output


Function: 2 Outputs


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”).

Function: 1 Output


T = t1 + t2 +...

Function: 2 Outputs


T = t1 + t2 +...

Function: 1 Output with Retrigger / Restart Control


T = t1 + t2 +...

Function: 2 Outputs with Retrigger / Restart Control


T = t1 + t2 +...
