ON-delay timing for SIRIUS contactor assemblies
The 3RA2831-1DH10 is a SIRIUS function module that adds an adjustable ON-delay to a contactor assembly — the delay range spans 0.05 to 100 s, set via a potentiometer on the module face. Clip-on mounting to the contactor means no DIN rail space is consumed — the module snaps directly onto the SIRIUS 3RT2 contactor front, keeping the panel layout tight.
Timing behaviour and recovery
This is a pure ON-delay function — the output switches after the set time when control voltage is applied, with no OFF-delay or pulse-shaping modes. The recovery time between cycles is 50 ms, which governs how quickly the timer resets after the control voltage drops. The module can be mounted in any orientation, matching the contactor's position flexibility.
