Technical Specifications Coil voltage: 24 V DC ±10%; Contact configuration: SPDT; Contact rating: 5 A resistive at 250 V AC, 3 A at 30 V DC; Delay range: 0.1 s to 100 s field-adjustable; Delay accuracy: ±5% of setpoint; Operating temperature: -40 °C to +70 °C; Enclosure rating: IP20; Mechanical life: > 1,000,000 operations.
Functional Features Selectable on-delay / off-delay operation; field-adjustable delay via potentiometer; precision electronic timing circuit; LED status indication; built-in coil surge suppression; DIN rail mountable.
Application Scenarios Engine start-up sequencing, protection delay coordination, alarm verification delay, sequential machine control, pump and compressor start staging.
Performance Parameters Delay repeatability: ±2% of setpoint; Contact operate time: < 10 ms; Contact bounce: < 3 ms; Reset time: < 50 ms.
Material Composition Flame-retardant plastic housing; precision timing IC circuit; electromechanical output relay; adjustment potentiometer; surge suppression diode.
Structural Characteristics Standard DIN rail mount form factor; front panel delay adjustment knob and status LED; rear screw terminal block; integrated DIN rail mounting feet.
Working Principle When the coil is energized, the internal timing circuit starts counting. After the preset delay elapses, the output contact switches state. In off-delay mode, timing initiates on coil de-energization and the contact resets once the delay expires.
