The 80.010.4005.0 is a 12 V AC/DC relay module designed for industrial control and switching applications. It features a single changeover contact (SPDT) rated for 250 V AC / 300 V DC at 6 A maximum switching current, with a maximum switching capacity of 1500 VA / 48 W. The module operates with a nominal input current of approximately 14 mA and nominal input capacity of 0.35 W, with a holding current greater than 1.2 mA at 20 °C. It provides fast response with pickup/dropout delays of 8 ms / 10 ms, a chatter time of 2 ms, and supports a maximum switching frequency of 20 Hz. The relay module measures 6.2 mm overall width with dimensions of 6.2 × 89 × 70 mm and is available with screw or spring-clamp terminals. It is suitable for DIN rail mounting (TS35) with IP 20 protection, operates across 0 °C to +50 °C ambient temperature, and includes a green LED status display for operational indication.
