Siemens 3RA28 Series Electronic Timing Relay, 0.05 to 100s time range, 24 to 240V control supply - 3RA2811-1CW10
This electronic timing relay provides ON‑delay timing for control circuits. It accepts 24 to 240 V AC/DC supply at 50/60 Hz, features a semiconductor output for contactor control and an integrated varistor to damp contactor Coil transients. The device clips onto compatible contactors and is suitable for use where compact, front‑mounted time control is required.
Features and Benefits:
• 0.05 to 100 s adjustable time improves process synchronisation
• Semiconductor output gives low voltage drop and 3.5 V maximum when switched through
• Integrated varistor reduces contactor Coil spikes, supporting Coil longevity
• Semiconductor output gives low voltage drop and 3.5 V maximum when switched through
• Integrated varistor reduces contactor Coil spikes, supporting Coil longevity
Applications
• Used with S00 and S0 frame contactors for delayed start
• Ideal for sequencing contactors in motor start or machine control
• Ideal for sequencing contactors in motor start or machine control
What is the typical electrical endurance with matched contactors?
It typically achieves 10 000 000 operating cycles when used with S00 or S0 frame contactors.
What environmental and mounting limits apply to its installation?
It operates from -25 to +6 0 °C, can be mounted in any position, and is suitable up to 2 000 m altitude.
