£47.40
The ABB 1SVR550100R2100 is a compact and reliable electronic time relay designed for precise timing control in industrial automation, electrical control panels and machine control applications. As part of the trusted ABB CT-E timer relay series, it provides an accurate ON-delay timing function with dependable switching performance for professional control systems.
This timer relay provides an ON-delay (delay on make) function, where the output relay energises after the preset time delay once the control supply is applied. Its compact 22.5 mm housing, DIN rail mounting capability and screw terminal connections make it easy to integrate into industrial control cabinets.
With an adjustable time range of 3–300 s, a 110–130 V AC control supply and a 1 changeover (SPDT) output contact rated at 250 V / 4 A, the ABB 1SVR550100R2100 is ideal for automation systems, sequencing applications and industrial electrical installations.
Electronic timer relays such as the ABB 1SVR550100R2100 provide accurate control of electrical switching sequences by introducing controlled delays into automation circuits. This enables improved process timing, machine coordination and reliable operation of industrial systems.
The ABB CT-E timer relay range is designed for professional control panel applications, offering compact dimensions, dependable switching and straightforward DIN rail installation for industrial automation engineers and machine builders.
