Elmex Industrial Automation Control Products

Introduction

In the field of industrial automation control, components such as timers, protective relays, and transmitters are key to achieving precise control and safe system operation. Since its establishment in 1963, Elmex has been committed to providing highly reliable, compact, and easy to install control products. This article is based on the Elmex IFM product catalog, systematically summarizing the technical characteristics, application scenarios, and specification parameters of its core products, providing professional references for engineers, system integrators, and OEM manufacturers.

Star Triangle Timer Series

Star delta starting is a common way of starting electric motors, especially suitable for high-power motors. Elmex offers multiple star delta timers, all designed with a 17.5mm ultra-thin DIN rail installation to save control cabinet space.

1. SD-A-R1-P13 Star Triangle Timer

This model is suitable for star delta starters and has the following characteristics:

Output configuration: Star mode 1 NO, Triangle mode 1 NO

Time setting: Triangle mode delay time T1 is 1.5 to 150 seconds

Pause time: Fixed 60 milliseconds

LED indicator: There is a red LED indicator light for both star mode and triangle mode

Protective design: The front cover can be sealed to prevent accidental operation; Support measuring parameters with multimeter probes

Power specifications: Supports 240V AC or 24V AC/DC, frequency 50/60Hz, power consumption ≤ 8VA

2. SD-D-R2-P24 Star Triangle Timer

This model is similar to the previous one, but with an output of 1 C/O (conversion contact), providing a more flexible wiring method.

Time setting: T1 can be selected from 3-30 seconds or 6-60 seconds

Pause time: 50 milliseconds or 100 milliseconds optional

Application tip: External short circuiting of 15-25 terminals can achieve common pole connection

3. SD-A-R1-P35 Star Triangle Timer

On the basis of retaining the first two functions, this model has added a wider range of pause time adjustment:

Pause time: 50 to 500 milliseconds, adjustable in increments of 50 milliseconds

Applicable scenarios: Suitable for motor control scenarios with precise control requirements for start-up transition time

On Delay Timer

Elmex offers multiple power on delay timers, suitable for control scenarios that require delayed startup, such as sequential startup of fans, pumps, conveyors, and other equipment.
