Hybrid Power Relay (HPR)

Configurator

A programme for configuring the HPR10 is available on the E-T-A

website. It allows selection of various functions and sets up the

corresponding ordering code.

ON/OFF switching delay

The relay features a timer function allowing delayed switch on or off

of the load, e.g. for applications with exhaust aftertreatment (SCRT

catalytic converters).

This function allows delayed switch-on of the relay. The configured

value indicates the time elapsing between activation and switch-on.

Information: Thus the relay may for instance give time to other system

components to carry out their start-up, probably attenuating the

inrush current peak in the entire system.

This function allows delayed switch-off of the relay. The configured

value indicates the time elapsing between activation and switch-off.

Information: An overrun is desired in many applications, e.g. to give

some orientation with illuminations even after switch-off or to give a

load enough time to complete the switch-off process.
