It provides a timed auxiliary contact that closes after a set delay when the main device picks up. The delay is adjustable from 5 to 100 seconds, set via a potentiometer or DIP switch on the module. The ON-delay means the contact closes after the delay period once the coil is energized; there is no OFF-delay function.
The auxiliary contact is rated 1 A at 24 V DC, 0.2 A at 125 V DC, and 0.1 A at 250 V DC. These are the switching capacities for DC loads — the current drops as voltage rises because of arc extinction limits. For a 24 V DC control circuit, the contact can handle 1 A, which covers most PLC digital inputs and relay coils. The IP20 terminal protection means it's safe from finger contact but not from water ingress — install inside a panel. It mounts via clip-on to a DIN rail or directly onto a SIRIUS contactor. The dimensions are 45 mm wide, 38 mm high, and 75 mm deep, so it occupies one standard modular width.
This auxiliary switch is used in motor control centers and panel builds where a delayed auxiliary contact is needed — for example, to sequence a star-delta starter, delay a fan start after a pump, or interlock a secondary process. The clip-on form factor means it integrates directly onto a SIRIUS contactor without extra wiring.
