Relay for delayed Y/Δ motor start TRS2D

TRS2D is a time relay designed for delayed reconnection from star to delta connection during motor start up. It is possible to set time from 0.1 sec to 10 days for start connection and delay from 0.1 to 1 second for reconnection between star to delta. The relay has one output double-throw contact 8 A.

Time relays have universal power supply circuit available for AC and DC voltage in range 12 ... 230 V.

Time relays are equipped with operation status and LED optical signalisation for easy operation and service.

  • adjustable timer 0.1 s ... 10 days
  • adjustable time of Y/Δ reconnection 0.1 s ... 1 s
  • universal power supply 12 VAC/DC ... 230 VAC
  • relay output contact 8 A
  • small dimension 1-module on DIN rail
  • status optical LED signalization

Function

When the supply voltage is connected to the relay, contacts 17 - 18 are closed and the relay reads the set time of starting the motor to the star. After this time expires, contacts 17 - 18 are disconnected and the set delay between star and delta switching begins. After the expiration of this delay, the relay closes contacts 17 - 28 for the motor to run in a triangle.
