Sizing the ON-delay for your control sequence
The 3RT1926-2EJ31: It clips onto a 3RT1 contactor and provides a timed N/O or N/C signal after the contactor coil energizes — useful for staggering motor starts or sequencing downstream actions. The delay is set via a potentiometer on the module, with a recovery time of 150 ms between cycles. There is no OFF-delay function, so the output resets immediately when the contactor drops out.
Contact ratings and wiring terminals
The switch contacts are rated 3 A maximum at 24 V DC, 1 A at 24 V, 0.2 A at 125 V, and 0.1 A at 250 V. These are the thermal current limits for the auxiliary contacts — the actual switching capacity depends on the load type and voltage. The fastening method is clip-on, meaning it snaps directly onto the contactor without tools.
The module measures 33 mm wide, 46 mm high, and 73 mm deep. Pollution degree 3 (industrial environment with conductive pollution) and basic insulation — suitable for standard control panels without special coatings.
Same part, different passport — this is a genuine Siemens SIRIUS module, sourced through independent distribution channels.
