Acti 9 iRT, iRBN, iRLI, iRC

Timer/power relay modules

Part of 9 Series

Acti 9 DIN rail timer/power relay modules for automated system control, automated system monitoring and changeover circuit control.

Acti 9 iRT, iRBN, iRLI, iRC
  • Features

    Time delay relays:

    • Acti 9 iRTA: delays energizing of a load
    • Acti 9 iRTB: delays de-energizing of a load upon contact closing
    • Acti 9 iRTC: delays de-energizing of a load upon contact opening
    • Acti 9 iRTH: delays de-energizing of a load
    • Acti 9 iRTL: repeated energizing and de-energizing of a load (flasher)
    • Acti 9 iRTMF: can be set to perform any one of the iRTA, iRTB, iRTC or iRTH functions.

    Interface relays

    • Acti 9 iRBN: low-voltage input, low-level output
    • Acti 9 iRTBT: low-level input, low-voltage output.

    Control relays

    • Acti 9 iRCI: current threshold
    • Acti 9 iRCU: voltage threshold
    • Acti 9 iRCP: phase threshold (motor monitoring)
    • Acti 9 iRCC: detection of power cuts and voltage dips (compressor monitoring).

    Changeover relay

    • Acti 9 iRLI


    Acti 9 DIN rail timer control power relay modules offer:

    • A wide range of automatic control functions
    • A front face indicator to monitor the product status
    • A front face cover to protect against unintended operation of the timer controls.


    The Acti 9 DIN rail timer control power relay modules provide various types of automatic control for use within industrial and commercial buildings. These include the following:
    • Lighting
    • Heating, ventilation, air conditioning
    • Watering
    • Automatic door opening/closing systems
    • Control of other repetitive timed systems.
