Product Description:
The EL2042 EtherCAT Terminal is manufactured by Beckhoff with high output reliability. It has two independent 24 V DC outputs with 3-wire connection technology. Each channel supports a maximum output current of 4.0 A. Both outputs can be connected in parallel for up to 8 A total. The terminal provides short-circuit protection with a typical current below 70 A. It includes reverse voltage protection for safe operation.
The EL2042 EtherCAT Terminal supports each channel that allows a breaking energy of less than 1.7 J. Typical switching times are 40 µs for turn-on and 200 µs for turn-off. This terminal consumes approximately 120 mA from the E-bus system. The E-bus and field potential are electrically isolated at 500 V in the terminal. It has a power contacts that require around 15 mA plus the output load. The bit width in the process image includes two digital outputs. It ensures robust performance in industrial environments. The EtherCAT Terminals are housed in durable polycarbonate material. The unit weighs around 55 g and supports flexible installation positioning. It has dimensions of 12 mm width, 100 mm height and 68 mm depth. The device installs on a 35 mm DIN rail. A side-by-side mounting is safe with a double slot and key mechanism. The Terminal is dependable at temperatures ranging from 0°C to 55°C. It has storage temperatures from -25°C to +85°C.
The EL2042 EtherCAT Terminal handles 95% relative humidity without condensation. The maximum current load that power contact terminals can handle is 10 A. The terminal is compliant with EN 60068-2-6 / 27 for vibration resistance. The protection rating is IP20 for standard control cabinet environments. The EMC immunity and emission align with EN 61000-6-2/4 standards.
Frequently Asked Questions about EL2042:
Q: What is the advantage of using 3-wire connection technology in EL2042?
A: The 3-wire system allows for simplified wiring with clear separation of signal and power, enhancing both safety and diagnostic capabilities during field installation.
Q: How does the 500 V isolation benefit the EL2042 EtherCAT Terminal?
A: This isolation prevents signal interference between field devices and the control bus, ensuring clean communication and minimizing the risk of cross-voltage damage.
Q: Why is reverse voltage protection important in EL2042?
A: It prevents damage to internal electronics caused by incorrect wiring or reverse polarity, increasing product longevity and system safety.
Q: How does the EL2042 support flexible mounting configurations?
A: Its compact 12 mm width and double slot/key mechanism enable secure, space-saving side-by-side installation on DIN rails in tight control cabinets.
Q: Why does the EL2042 have separate power contacts drawing up to 10 A?
A: It separate power contacts help isolate load power from logic control, allowing better current management and supporting high-load peripherals.
