ABB Timer Relay, Time Range 0.05s to 10 min, Supply DC/AC Voltage 24 to 240V AC/DC - 1SVR730211R2300 CT-SDS.23S


This timer relay is designed for star-delta motor control and general sequencing in industrial electrical panels. It operates across a wide supply range and provides a selectable timing interval for controlled transitions between motor starting modes. The unit is intended for DIN-rail installation and suits environments requiring moderate ingress protection.

Features and Benefits:


• Time span adjustable from 0.05 s to 10 min for precise sequencing
• Dual supply compatibility 24 to 240V AC/DC for flexible installation
• Two changeover contacts carrying 4A for modest control loads
• DIN-rail mounting in 22.5mm width for Compact panel design
• Operates between -25 to 60°C for varied ambient conditions

Applications


• Suitable for star-delta motor starting circuits
• Used with contactors in industrial motor-control panels
• Ideal for replacing mechanical timers on production lines
• Can be used for timed switching in HVAC control systems

What contact configuration does it provide?


It provides two changeover contacts rated to switch currents up to 4A each.

How is the unit secured inside an enclosure?


The device clips to a DIN rail and occupies 22.5mm of rail width.

Which standards govern its construction and flammability?
