Siemens 3RA2811-1CW10 ON-Delay Electronic Timing Relay
Siemens 3RA2811-1CW10 ON-delay electronic timing relay.
The Siemens 3RA2811-1CW10 is an electronic timing relay featuring an ON-delay function. It provides a time range from 0.05 to 100 seconds, with a wide operating voltage of 24-240 V AC/DC and 50/60 Hz frequency. This relay utilizes a semiconductor output and includes an integrated varistor to suppress voltage spikes from contactor coils. It is designed with screw terminals and can be directly snapped onto Siemens 3RT201/3RT202 contactors and 3RH2 auxiliary contactors.
This ON-delay timer is suitable for a wide array of applications requiring precise time-based control, such as pre-heating, motor start sequencing, sequence control, and delay functions in industrial machinery, HVAC systems, and automation processes.
