INSTALINK-SRM Sequencing Relay Module

Brand: Emphatec
Add Product to My Catalog

The INSTALINK-SRM was designed as a power supply accessory but can be used in any application where it is desirable to switch on 24 Vdc loads sequentially. 

In the case of DC power supplies, some loads may actually switch on and draw current when the power supply voltage is at a fraction of the normal output. For example, when a power supply is switched on the voltage ramps up to 24 Vdc but an Analog signal conditioner may start drawing current when the voltage is 10 Vdc or less. 

If the signal conditioner has an internal DC/DC converter (many do) the current draw at 10 Vdc is substantially higher than at 24 Vdc. If there are too many loads like this it can cause the power supply to go into an overcurrent condition and shut off or the voltage will never increase to 24 Vdc.
Features
  •  Time delay turn-on relay modules.

  • Designed to sequentially energize loads.

  • 24 Vdc power is easily jumpered to adjacent modules. Jumpers are included.
