YRA006 · ALTERNATING RELAY FOR THREE MOTORS (PLUG-IN CONNECTORS)

YRA006 alternating relay for 3 pumps: up to 3 outputs on at the same time, with 5 s between starts. DIN rail, plug-in connectors.

Features

• ✓Each pulse on an input starts the next pump: all three share the running hours
• ✓Up to 3 pumps running at the same time depending on the active inputs
• ✓Outputs never start together: 5 s offset between starts
• ✓Optocoupled inputs, 3.5 kV isolation
• ✓Multi-voltage with transformer: 24, 48, 110, 230 or 380 VAC and 12 or 24 VDC
• ✓Supply and output status LEDs
• ✓Plug-in connectors: wired in the workshop and replaced on site

How it works

1. 1Each time a pulse reaches an input, the YRA006 connects the pump that is next in the sequence.
2. 2If one input is active and another one is activated, the corresponding output connects and both pumps run together.
3. 3If two or more inputs are activated at the same time, the outputs start 5 s apart, beginning with the one that is next.
4. 4This avoids starting peaks and equalises the hours of the three pumps.
