The Grove 2-channel SPDT relay has two single pole Double Throw (SPDT) switches. Only low voltage and low current signals are required to control these switches. In particular, you can use 5 V DC to control max. 250V AC or 110V DC. features - high temperature resistant plastic cover - high-voltage load - low power consumption - long-lasting - Channels separately controllable Technical data - Operating voltage: 5 V - Rated coil current: 89.3 mA - TÜV certification Load: 10 A / 250 V AC, 10 A / 30 V DC - UL certification Load: 10 A / 125 V AC, 10 A / 28 V DC - max. permissible voltage: 250 V AC / 110 V DC - Power consumption: approx. 0.45 W - Contact resistance: max. 100 mOhm - Insulation resistance: min. 100 MOhm (500 V DC) - max.
