Relay timers, also known as time delay relays, timing relays, or timer relays, are essential components in industrial automation and control systems. These devices are designed to control the timing of electrical circuits, providing precise delays for switching operations. Common types include on-delay, off-delay, interval, and star-delta timers. They are available in various configurations, such as multifunction timers, single-function timers, and programmable timers, with adjustable time ranges from milliseconds to hours. Key technical specifications include supply voltages (e.g., 24V DC, 110V AC, 230V AC), contact configurations (e.g., 1CO, 2CO), and mounting types (e.g., DIN rail, panel mount). Relay timers are often integrated with contactors, motor starters, and PLCs to enhance system functionality.
Relay timers are widely used in industrial automation, building management, and process control applications. They are commonly installed in control panels, distribution boards, and motor control centers (MCCs). Typical sectors include manufacturing, water treatment, HVAC, energy management, and transportation. In automation systems, they control sequence operations, delay motor starts, manage lighting schedules, and protect equipment from short cycling. They are also critical in safety circuits, where precise timing ensures safe machine operation and emergency shutdown sequences.
Our inventory includes a comprehensive range of relay timers from leading manufacturers. Subcategories include multifunction timers (e.g., KETR series), single-function timers (e.g., KEMR series), and star-delta timers (e.g., KESR series). Key article codes often follow a pattern like KETR-1CO-24V, where 'KETR' denotes the series, '1CO' indicates the contact configuration, and '24V' specifies the supply voltage. Other common codes include KEMR-2CO-230V and KESR-1CO-400V. These timers are available with adjustable time ranges, LED status indicators, and screw or spring clamp terminals.
