ABB CT92474A

1. Precision timing control architecture

ABB CT92474A is the core model of ABB CT series electronic time relays, using industrial-grade digital timing chip and anti-interference circuit design. It supports 24-240V AC/DC wide voltage input, built-in voltage adaptive voltage regulator module, to ensure ±0.1% timing accuracy under ±15% voltage fluctuation. Its innovative 7-segment programmable time range (0.05 seconds to 100 hours) covers the needs from millisecond-level mechanical control to long-cycle process management, and realizes intuitive parameter setting and operation status visualization through direct-reading scale knob and LED status indicator

2. Multifunctional timing engine

19 delay modes integrated:

The module has built-in 19 control logics such as power-on delay/power-off delay/pulse trigger/star-delta conversion, among which ABB CT92474A's unique dual-mode seamless switching technology can cope with emergency switching of production lines

Anti-interference redundant output:

Equipped with 1C/O or 2C/O gold-plated contacts (load capacity 5A/250V AC), arc suppression technology and double overload protection are adopted. The mechanical life of the contacts is up to 1 million times, and the electrical life is still maintained at 100,000 times in an environment of -40℃ to +85℃

Intelligent interlocking control:

Supports remote potentiometer connection and external control input contacts, and realizes remote control of timing start/stop/pause through voltage-independent contacts. ABB CT92474A's unique instantaneous contact auxiliary output function can synchronously trigger secondary equipment within a time period to improve production line coordination efficiency

3. Industrial-grade enhanced design

Environmental adaptability: The fully sealed IP54 protective shell resists dust, oil mist and acid and alkali corrosion, and passes the EN 60947-5-1 vibration test

Safety certification matrix: Integrates 8 international certifications such as UL, CE, cURus, and complies with IEC 61810-1 electrical safety standards

Quick installation system: Provides dual options of double screw terminals and plug-in quick-connect terminals, and supports DIN rail clip installation

4. Cross-domain application verification

Automobile manufacturing: Welding robot beat control, coordinate 3 IRB 6700 robots to start and stop accurately in 0.2 seconds, and improve welding beat stability

Building energy: HVAC system pump group rotation, realize 24-hour intelligent cycle start and stop, reduce equipment wear and save 18% energy
