Product Positioning

The 3RT1926-2EJ21 is an energized delay auxiliary contact module used with Siemens SIRIUS large contactors. After the contactor coil is energized, the module will operate with a set time delay, providing one set of normally open and one set of normally closed contacts. It is suitable for circuits that require start-up sequence control, such as equipment start-up sequence or loop interlock protection.

Core Product Advantages and Features

On-Delay Function

The coil switches contacts with a delay after being energized, which is suitable for sequential start-up control of equipment.

1NO+1NC contact combination

It provides both normally open and normally closed contacts to meet various logic control requirements.

Delay range: 0.5~10 seconds

The delay time setting can be adjusted according to the process rhythm.
