NewTrend · Alternating-load timer relay
Product overview
NewTrend RT6-RL alternates two loads using a common operating interval t1 and a separately adjustable pause interval t2. The right load starts first with S-A1 open; linking S-A1 selects the left load first. Two SPDT outputs operate the separate load-control circuits in an 18mm DIN-rail housing.

Set the common load operating interval t1 and the pause interval t2. Choose the first load with the S-A1 connection. Use appropriate contactors and interlocking for the controlled equipment.
Operation
- With S-A1 open, the right output operates for t1; after the pause t2, the left output operates for the same t1 interval. The sequence then continues alternately.
- Connecting S-A1 reverses which load starts first. Refer to the load-contactor reference circuit for the terminal arrangement.
Typical applications
- Alternating operation of two loads
- Two-contactor sequencing
- Equipment requiring equal operating periods with a pause between loads

Two-load contactor reference circuit
Set the common load operating interval t1 and the pause interval t2. Choose the first load with the S-A1 connection. Use appropriate contactors and interlocking for the controlled equipment. Each interval equals its selected range multiplied by its 10%-100% fine adjustment. Installation and wiring must be performed by qualified electricians.
