The EL2024-0010 digital output terminal connects binary 12 V DC control signals to the actuators with electrical isolation. Four channels are available, which indicate their signal state via LEDs. The EL2024-0010 facilitates direct connection of four 2-wire actuators because it has four ground connection points.

Special features:

• 12 V DC outputs
• Connection of different load types possible (ohmic, inductive, lamp load)
• Max. output current 2 A per channel
• Short-circuit-proof outputs and reverse polarity protection
• Suitable for automotive applications, for example
