GT5Y-4SN6A24 is an ON-delay timer module with 4PDT (4-pole double-throw) contacts designed for industrial timing and control applications. The timer operates at 24V AC supply with a 6-second to 60-minute time range (6S/60S/6M/60M selectable), delivering 3A resistive load capacity at 220V AC or 30V DC, and 0.8A at 220V AC or 1.5A at 30V DC for inductive loads. It features a repeat error of ±0.2% maximum, temperature error of ±3% over -10 to +50°C, and a setting error of ±10% maximum, with reset times of 0.1 second maximum after time-up or 1 second maximum before time-up. The module includes power-on and timing-out LED indicators, hand or screwdriver-adjustable control settings, and is compatible with IDEC's RY4S and RU series relay sockets and hold-down clips. With 200,000 minimum electrical operations at 110V AC and 3A, and 50,000,000 minimum mechanical operations, this timer is ideal for process control, equipment sequencing, and automated industrial systems requiring precise timing delays.
